They put a screw in there so you drop it down the dash and spend days trying to find it.
i was thinking the same thing.!!!!!
Lol. Is true.
GM puts that screw there, because GM hates mechanics.
Engineeers punishing mechanics lol
If it was my car, I would leave it out as long as the tabs hold it.
your dedication for detail and customer service never ceases ray kudos to you!
I completely agree with you. Ray's attention to the specs, and rechecking when he doesn't feel something is right sets the standard.
paid by the minute
You're doing a good job but you don't know what you're doing.
I had invaluable mentors myself when I was in tech school that taught us how to not only fix it right the first time, but to always question the answer (instead of simply changing parts like a robot) to ensure what we were doing was indeed the correct course of action. This is the number one reason I love this channel so much because 99% of the time, Ray & I are on the same page! I will literally be sitting there watching a vid saying something to myself and quite literally 2 seconds later Ray is saying the exact same thing. The other 1% I can't help but REEEEEE, screaming at him through my computer that there's a better way! 🤣🤣🤣
[2 minutes laytehr] Ray: "Welllll, that didn't work...." Me: "Toldja!!!"
Wow! $1,600 for 10 lb refrigerant? At that cost we may be heading back to rolling down the windows and driving faster.😊
Bureaucrat's made this happen.
3m's profit margin was getting low or the Patten was running out
That 10 pound can of 1234YF does not cost you 1600.00$. My cost at Oreilly's is 599.00$. I am a master tech with 32 years experience in this field as well as having the joke of a license to be able to buy it. Be honest with your viewers. Whatever you sell it for is your business. Also not sure why your machine does it like you claim it does but my snap-on machine will charge a small amount of 1234 to the system then make you turn on fan and send airflow to floor. Then using a sniffer check for any leaks. If no leaks are found by the tech then you simply press continue and the machine releases the rest of the charge. The only time it will not allow you to charge is if during the vacuum process while it is monitoring the micron level it rises above a predetermined set point thus causing the machine to terminate the process until you find the leak. Other than that I love watching your videos and amazed at how far you have come.
@@luthergrant7336 Thats what I ws screaming I replaced my condensing coil on 17 silverado and think I bought 3 cans at 55.00 can? was they 12oz? used little over two of them? That was last year.
@@dgc940 I know that's my small problem with Ray. Sometimes he will exaggerate things to make something seem more than it is. Maybe for views I'm not judging. Just something I have noticed. Nothing against the man in any way what so ever. I know it takes a considerable amount of time to film, edit and post videos and I can only imagine how busy he is. I appreciate him posting videos for the world to see and learn from. He obviously works his butt off. There's a difference between what it costs and what hes selling it for. Obviously say this is what i sell it for instead of it cost me. It misleads people.
Hello there Ray. I'm a retired HVAC technician. Going to the filter first is the right call. Second, I would have checked the condenser fin conditions. A dirty condenser will keep high side pressure very hi, even if the engine/condenser fans are working ok. With a clean filter and clean condenser you can then measure the refrigerant charge without worrying of these factors. Anyways, you do a great job always and I love your channel. Keep it up!
ANY EXPANSION VALVE SYSTEM should have a sight glass on it,, then no need to remove, weigh and recharge. I think the metering device is beginning to fail. 300 high side is too high.
these are the type of comments that I love to see, helpful tips on the work. Thank you for responding with this. It does help and people do read it!
exactly
Pro tip Ray, those A/C machines will fill their internal tank much faster if you flip the source tank upside down. Our machines actually say to do this in the instructions. On a side note, that machine is a piece of junk. Our Robinair 1234YF machine is slow but not nearly that slow.
Some machines you can't fill with liquid. Mine specifically says to ONLY fill using vapor, although it is a R-134 and not 1234yf.
faulty pressure gauge reads high?
Interesting, I was told to fill with an upside down bottle.
@@EvrttGrn Wonder what the "YF" stands for, Oh, I know you're F'd!
@@EvrttGrn Both our R134A and R1234YF machines fill with the tank upside down. The same was true with our old R12/R134A combo machine.
Have to hate those hurry up and wait jobs. Well done Ray, for sticking with it and not just going crazy with frustration.
Has to be one of the "easiest" all-day jobs.
Just press START and swear at the machine for hours.
R1234yf costs no more to make than R134a, its expensive because DuPont/Honeywell are making bank while it's still under patent. We've got to wait until 2030 when the patent expires.
I figured it was so expensive because of some sort of BS patent issue. Problem is by 2030 another new refrigerant will probably be mandated (R-700-something, I think Mercedes already uses it) and the whole process will probably repeat
Thats why they make new refrigerants before the patend ends. The new refrigerants is not better. Its just patented. Money money it is.
@@chrisfreemesser5707But R744 is just CO2. The systems and parts for running it are very expensive because of the 1500psi high side pressures but there's no way to patent CO2, it's just used for too many applications. You could easily just get it at your local welding shop for very cheap. But the parts cost on those systems will be insane, even though the refrigerant cost is low.
I am now impressed with the shop and how much more organized it is and take back anything negative i said before about being unorganized. I now realize that with doing the work and videoing and editing there could not have been much time for cleaning organizing and putting. Your hired help is doing a great job I bet you even notice that it's nice to find your tools where they're supposed to be 👍
Keep up the great work and fantastic videos.
If Ray organized his tools he'd never find them.😆
Given there are multiple people in the shop, I'd put labels on the drawers so things go BACK where they belong (and for me, because I always forget where things are and end up hunting)
mechanicing is slower and if you slack on video editing you wind up with hours upon hours of video to go thru.
I feel your pain Ray, for AC work I use digital gauges that handle different refrigerants, separate recovery machine suitable for flammable refrigerants and OFN (nitrogen) for pressure testing. Love your videos, Best wishes from UK.
So when Ray says it’s blowing cool at 40°, you probably have to do a double-take, huh? ;)
It's always the "simple jobs" that'll get ya.
Indeed!
Simple... does not mean easy. :(
The sad part is you could have completed like 7 or 8 oil changes in the time you were relaxing on the lawn chair drinking a beer while waiting for that slow A/C machine to finish what it was doing lol.
Dont tell all my secrets Shhhhhhhh
Wonder how only Ray has commented on this…
So if this a/c system takes all day to recharge, do you bill the customer for 8 hours labor. And how would a mechanic getting paid book time get paid time wise.
"I'm not an engineer, I just work here." LOL Chances are the design engineer of this car couldn't change this filter.
over here in mexico the 1234yf freon is too expensive its about 120 usd for 10 oz can, we have been retro fitting to r134 with some adapters. pressures are about the same we just cut back 10% and watch the pressures for about 30 mins.
Where are you getting the adapters?
Ray is rare kind of mechanic who is thorough and spends as much time that is needed to get the job done right. He even went back to check the specs on all data because he didn’t trust the sticker. Most mechanics wouldn’t have done a thing to this truck and would have charged a diagnostic fee. Ray is one of the best out there.
When running your own shop, a mechanics reputation is everything, Word of mouth will make or break a mechanic with his own shop.
So true
He skipped the confirm the complaint before you touch anything not after you toss a hepa filter in a skewed diag thought .
Integrity is not a quality everyone is capable of retaining. Becoming like every other mediocre person is much easier than having impeccable integrity. It’s more work to keep your integrity but it’s well worth your effort. Ray has integrity and definitely retains it every time he completes a job.
Okay, mechanics out there! HOW MANY OF YOU HAVE EVER FOUND *GLOVES* IN THE GLOVE COMPARTMENT???
I have gloves in mine - when passengers open the glove compartment they giggle
It’s usually stuffed with papers and all kinds of random crap. There’s usually something sticky in there too. I keep my gloves under the spare tire cover/trunk panel.
Hey Ray, how about a video of a wheel bearing replacement and wheel alignment for your yard fence gate (12:34)?
OMG 12234YF - a million times more costly than normal 😢
Love your dedication to the customers.
I almost miss the glove box doors of old, where the latch would suddenly open and the door would slam you in the knees
good ole days
Made out of steel so it could develop some real velocity with its razor edge.
@@kenore4003 yes sir!
I once put an 8-track in the glovebox of my 65 Chevelle. I miss those days.
Or the old ones that opened flat that had insets in the metal for your drink when you were served at the drive-in.
You want to save the customer money convert it backwards to R134 the oils for 1234YF are compatible. Of course recover all the 1234yf(never mix the 2 ever) out of the system flush the lines and stuff. I have saved my customer hundreds by doing this.
Well dang. I'd buy you a cookie but I don't know what they are putting in those things these days either. Good tip.
R-152a works even better if you’re making substitutions.
@@seanwieland9763 Interesting and its pretty cheap per oz.
Point blank DuPont and whomever else was involved in 1234yf sucks there was absolutely no need to change refrigerant we could’ve still been using R12 be a freezer in 5 minutes
All a hoax and a money grab. Hole in the ozone my ass
Happy 4th July, Ray. I know it's a big thing for you guys over the pond. Love from 🏴 (hope we get ours one day)
It's odd that the new machines fill with the bottle right side up. My Robinair requires the canister be upside down. The hissing in the dash could be an evaporator leak. 1234yf high side psi should be around 250 at 90* F. 325 seems high. Either overcharged or expansion valve.
Now that lost plastic cap on the A/C service port will lodge itself somewhere with moving engine parts (Murphy’s Law), get crunchied, then seize up the engine. Oh, no! Then Ray will have a come-back. 😢
The screw is there so when both clips are broken off there is still something to hold the door in place.😁
What if the clips break and you drop the screw into the dash lol
Except that by that stage, if the clips have broken off, chances are that the thread in the plastic is also worn off and it no longer holds! That's why when putting them back those screws need to be rotated anti-clockwise until they click so you know you are going into the same threads in the plastic each time. Not many people do that: they just screw away!
@@heckelphon I didn’t know that about screws threaded into plastic. Good to know.
@@jeffsullivan3101 I've not met that many engineers who did! The thing is with those fastenings that they can be driven in super fast in assembly as the hole is just a smooth drilling at that stage, and they hold secure, but if they have to come out more than just a few times they can easily get slack unless you match up the threads. If you chew away the old thread by driving a new one too often you have to end up substituting a metal screw with a threaded insert using a bit of heat, like from the end of a soldering iron. That can be easy if it's a soft polymer like ABS, but if it has too high a melting point you can be in trouble. And some fastenings, like on cheap UPS cases, just shatter the second time you undo them to replace the battery in any event!
Since the charge was low check the rear evaporator for evidence of dye. May need to add some dye and recheck. You can pull out the rear blower motor and get access to look. They are common for leaking on this body style and I believe there's a bulletin for it too. We've done lots of them at the GM dealerahip. Just a possible idea
There's 2 evaps in that little thing?
Wow, I thought that was a big vehicle thing.
Thanks for posting all they see here still learning I try to help people
@@volvo09 With it being an Enclave, that's not that surprising. Those are about the same as a Traverse, third row seating and all, so yeah.
Did your client stroke out when he got his bill for hundreds of dollars for the 1234YF? That’s absurd. OK, I understand the need to get rid of the chlorinated R12 to help out the ozone layer, but damn.. more than a hundred dollars a pound? How much did DuPont pay off the Biden family in Delaware! Millions of cars at a couple of pounds for each car adds up pretty quick. Who is responsible for this one? I didn’t even know that they had changed to a different refrigerant. Why? What was wrong with the old one?
Nothing wrong with 134a. Most likely a scam to generate "new money".
Whenever I replace filters, I always put the date and mileage on them.
Fixing & recharging 1234YF systems is so expensive, older vehicles with it will be scraped , replaced. It's use is really stupid from a consumer standpoint.
Great Contant, I recently recharge my Dinali with 134a instead of the 1234 and the pressures are same so 1234 is flammable and I prefer the 134A and I didn’t change anything
I'm curious to try it, but again, Publishing such things could get a knock on the door by the alphabet boys these days.
If you flip the old filter upsidedown, you will discover that it is self cleaning.
Shop has changed so much since opening. Already expanded and hired two employees.
Who's the other guy
His wife
and the fuzzy feeling I'm getting here in Victoria Australia ... is that we all know these two new guys are getting the correct training and ethics
@@major__kongI noticed another woman vacuuming in one of the videos. He actually had to talk over the vacuum
@@frankcrenshaw7343 Amaya (spelling?),she helps Lauren in the office.
Love your thoroughness on every symptom that you find. Thank you for sharing your livelihood and passion with us.
I just had this same problem in my 2013 Ford Escape SEL. The evaporator was freezing up an causing airflow to be blocked. Only happened occasionally on hot days and stop and go traffic. Did some googling and found out it was the EVAPORATOR DISCHARGE TEMP SENSOR. Replaced and worked great.
A clogged filter will cause the unit to freeze up.
I agree. I replaced it before I had the problem.
I don't know much about vehicle AC systems, but they're probably similar to AC in a building. There's usually a temp sensor on the coil, and if everything's working right, the coil won't ice up no matter how clogged the filter is. The switch cuts the compressor off when coil temp reaches +3C or so, a few degrees above freezing. No matter what's going on with airflow.
1234yf is Very annoying Especially being its 50 times slower and all the safe guards and How pricey it is compared to R-134A I feel R-134A is better we been using it for 20 plus years @Rainman Ray's Repairs
Serious question...if there's no leak, where'd the original refrigerant go?
There are a lot of connections to seal on a car's ac system, and no seal is perfect. Even the ceramic seal on the ac compressor will leak a small amount. The amount lost adds up over the years and is unnoticed until enough is lost to degrade performance.
A LITTLE KNOWLEDGE IS A DANGEROUS THING and the government officials all have a little hence the regs we end up with
Typical scam in my opinion. The swap from 134A to 1234YF claims that it is more environmentally friendly, but costs three times the price. Just another way to get customers to pay more. The criticism isn't leveled at you, obviously, it's just another one of those things that proves how incredibly inefficient government interference tends to be. Great video
Want to hear more government interference? CAFE standards basically killed small pickups. Because the smaller wheelbase and track, the required MPG goes up - like the old mazda B2200 would need about 50mpg in order to not be penalized. That is why huge trucks are the norm - the bigger they are, the lower the acceptable mpg.
Often wonder.... will 134A work in a 1234YF system if you flush it, like we used to do with R12 systems when 134A became the cheaper option.
yes, r134a would work in place of 1234yf. but doing so is a federal crime. you'll loose your 608 certs and get huge fines. potentially jail time if you do it to a bunch of vehicles.
@@jankcitycustoms Is there no way to "backwards rtro-fit". Guess this leads to another question... if at some point 1234yf becomes cheaper.... could you legally retrofit a 134 system?
Not in the trade anymore, just do family/friends repairs as I can at home, but trying to keep up to date with the new stuff.....
legally, i think you could. however most of the new systems designed for 1234yf have an additional heat exchanger on the suction side. since systems designed for r134a do not have that. I think if you put 1234yf in a r134a system, it would perform very poorly.
While everyone is praising this “repair”, let’s look at the facts. Requires over 2lbs of refrigerant, only recovered .235 lbs. Where is the balance of refrigerant? It has either leaked out or the A/C machine is faulty. I know the machine supposedly pulled a vacuum to ensure no leaks prior to recharging, but the question remains….where is the missing refrigerant? My suspicion is that the A/C machine is fubar. How can you get 40 degree air from a system that only has 10% of the required refrigerant? Plus…initial pressures were good for both low and high side. Ultimately, the filter was replaced and more refrigerant was added. Where’s the actual problem? Small leak at the evaporator? What am I missing?
This promises to be a chilling video
Thank you for not blaming us enginerds for the switch to 1234YF. We can specifically blame European bureaucrats
Absolutely outstanding Ray another most excellent video but the most important thing is to have your self a great day Ray
You mentioned that refrigerant cost $1000 for a 10-lb vessel. The refill was a bit over 2 lbs, if I saw things right. Did the customer have to pay $200 for the 2 lbs of refrigerant? Is there a shop markup on refrigerant, say $120/lb instead of actual cost of $100/lb?
I am curious because a local shop had a fixed price of almost $200 to check and fill my AC unit, and I can't recall if that included the 'freon' or not, probably not. I thought that $200 recharge cost was too high, so I went to the discount store and bought a $28 kit which came with a pound of freon, and also bought an extra two pounds just in case. It took me all of ten minutes to do the test and refill, and another five or ten to read and comprehend the instructions before starting. I realize there are good reasons to have those pro level AC freon machines, but for my 22 year old Chrysler Cirrus, and us living on SS, I just did not want to spend the money for a pro service. If it blows warm again next year, guess which route I will take again...
The screws in the cabin air filter cover is there for center of gravity and stability., helps prevent roll overs….. science
I have 2 vehicles with 1234yf. Terrible stuff!! Molecules are small, and leaks thru o-rings and everywhere. Change receiver dryer, and replace with synthetic version in a can, and ends problem. Have not touched my once a year fix and fill, in over 3 years now. Ram, and Jeep are for sure going to leak
I see you finally had the new overhead door installed. When did that happen? Any video of the installation?
Looks great.
No I didn’t install it, left that to the folks that I bought the door from. I didn’t want to follow them around all day recording, so we missed out on that video
@@RainmanRaysRepairsHe never said you installed it. He said "you finally had the new overhead door installed"
System needing 2.42 pounds and it originally had 0.242 Pounds should of never cooled To 70 degrees let alone 40 degrees Interesting how it cooled so well being so low on a charge that's is a first one never seen thst before either 😳 🤔 @Rainman Ray's Repairs
Given the plugged state of the old filter, you could leave the plastic film on the new one, and it will pass almost the same amount of air and never get dirty again😂
That "just rolled in," "customer states...," whatever the YT channel is called had that (sort of - but worse) on a video, a while back. Only it was the *engine* air filter that was wrapped in plastic. More and more, I'm thinking that most people deserve the things that happen to them (the remainder deserve worse).
@@wesgregg6451 AND on a oil filter I saw once! Those idiots deserve to be charged double the hourly rate!
At the cost of $1000 a bottle. 1234YF.. the YF stands for 'Yer F*CKED"... damn expensive
The sound coming from the dash could be the evaporator. This has happened to me twice and both times it was the evaporator and it made those hissing noises, it also made the temps fluctuate. Hope this helps!
What was the evaporator doing? leaking refrigerant, thus a hiss sound?
@@danielgoodman3578 Yes and it would slowly leak out the refrigerant
@@ashregalado thanks for confirming :)
I replaced the cabin air filter on my daughter's 2013 Mazda 3. 45 mins later success! What a royal POS.
"I just stopped in to see what condition you're condition is in "😂
Later Kenny changed it to "Just stopped in, to see what condition my fried chicken was in" (when he operated his Kenny Rogers Roasters chicken restaraunts...He would do that, at various franchises, via announced suprise visits...
Many years ago I knew a Bronco that wasn't cooling right. Dealers couldn't find problem so owner sold it and my friend bought it. Took it to a good car A/C guy and he found electric magnet drive was cutting in and out on compressor when hot. Replaced it and it was fine.
Can you reuse the refrigerant you capture during the purge, or is it contaminated or otherwise unusable?
That fan is just at max all the time Holey smokes 300 Psi that is way to high bet it has the wrong Sticker Common issue with buicks @Rainman Ray's Repairs
That filter is why I replace the cabin air filter in every used car I have ever bought. I have yet to buy a car that had ever had the filter replaced. Makes you wonder if the filters the quick lube places always try to get people to buy really do get replaced when someone agrees to the service.
When I bought my 2018 focus I did a fluid flush a day a new set of filters. The cabin air filter I am sure was the factory filter as clogged as it looked.
Somehow I’ve yet to own any car that has a cabin air filter. Still used to them occasionally sucking in a few snowflakes in the wintertime and blowing dust in the summer.
The quick lubes place where I go has a window between the customer reception and waiting area that you can look through while they service your vehicle. I can visually see what they are doing, and have seen them change the cabin air filter when asked to do so. Also, when I have requested a fuel filter change, I have seen them perform the work so I know it is being performed.
@@ericknoblauch9195 Next time you are in there, look at the other people in the waiting area. Take note of how many of them are paying attention to the work being done. I believe most do there work you are paying for, but there are still some that don't.
There is one of those places near me that keeps getting caught sending cars out with only half the oil, no filters changed, and even loose oil plugs. This shop gets sued a couple times a year because of engines seizing due to the lack of oil in the engine. If they can afford to replace that many engines, how many cars are they charging for services that are not getting done?
Each time my Enclave makes the hissing noise the system is low. It is leaking from the rear evap. Twice it has gone out at 1,500 each time to fix. There is a new service bulletin to replace the rear fan to a closed unit. The open fan is discharging copper to the evap and causing it to leak. Mine is out again for the third time. 2012 enclave.
The new filter is much less efficient than the old one.
If you compare them side by side there are far less pleats on the new filter meaning far less surface area.
Well since the person never changed it ever, it’s probably best it has less pleats so it’s less likely to clog after 100k miles 😂
Not a bit driver unless it has changeable bits Lmfao 😂 that sir is a torx screwdriver @Rainman Ray's Repairs
Some drivers don’t realise how dangerous a contaminated cabin filter can be. My father kept complaining about having a sore throat and weeping eye, flu like symptoms, for months. I asked him if he ever changed his cabin filter. I checked it out, and found it, even worse than the one you changed. I put it in a biohazard bag and put a disinfectant bomb in the car, his symptoms cleared within days.
Texas air quality is shit without Canadian wildfire smoke so I change mine 2x a year. Gave a friend's 4Runner a once-over before she was taking a road trip. Everything looked good except for a squeaky belt so I threw that on. I asked if she ever changed the cabin filter. Her response? "Cabin what?" Needless to say like your dad's, what I pulled out made what Ray pulled out look brand new.
I have had cars where I have fitted new cabin filters and new engine air filters at the same time , then checked them 10000 miles later and the cabin one is caked solid , but the engine one is spotless ! I would have thought that the engine would have sucked in far more air than the interior fan In the same distance/time ?
@@bobgorman9481
They probably park under trees most of the time. All that stuff sits in the cow then eventually disintegrates and makes its way into the cabin filter.
Half onion overnight good for smells
1234YF is so stupid. its uber expensive. takes such a long time to recharge . need special machines just for that. its "enviormently friendlier" yet it is flamable. we just send people to another shop when they have that crap in their car. we havent invested in one of thsoe machinbes. Most of our customers have older bones that get towed in and drive away lol
Probably the evaporator. And the leak test will pass. You have to add dye and look for dye at the drain tube
Agree look for dye coming from evaporator tube
Because there are mechanics out there "NOT You Ray" that will recharge the system and send the vehicle out even with a leak. Waste of money and refrigerant.
Ray so glad to see your business growing...happy for you! Wish you were in my area. :(
So my friend brought me a 06 expedition sold it to me cheap because his mechanic said ti had a spark plug broke off in the headso i got a drill and reverse drill bit and it sucked in fast pulled it out that cap you lostwas in the spark plug hole I sold it back to him price + labor 😂
I can understand how the machine checks for leaks drive you crazy but there are plenty of mechanics who charge a/c systems even though they know there are leaks. You don't do it because you’re ethical. I’ve had mechanics do it to my car and you can watch a/c guys who work on home systems fill feon into systems that leak on RUclips all day long.
Love your channel! The videos are great. Wish I lived closer so you could work on my car ❤️
I'm one of those hvac techs who charge a leaking system at customers homes.
What you don't understand is that it can be very expensive to find and fix a leak and a lot of customers refuse the repairs and decide to just recharge the system. Everyone is working on a budget and not everyone is able to have us properly repair there system like we want. It is what it is, were at the mercy of our customers.
You would be surprised at how many work orders I have had the said charge a/c, customer knows it leaks.
it should be illegal and industry norm to not allow a refrigerant to escape from any leak. use your heads
@@tomblobasjamesc.mccollum1740 Get real, what do you think when a car gets in an accident, when cars go into the junkyard
@@nd3498 The answer i came up with is use red tec the eco freon replacement, in most systems that are low a can of sealant and a recharge with it and the system is good for years with no other maintainence ,just tag it so no one mixes coolant by mistake ,i have done multiple systems this way for over 25 yrs. . and the coolant is so cheep .

@@legogummybear5Right on red has been around since the 1970s. It was introduced during the 1973 Arab oil embargo as a fuel saving measure.
@@spaceflight1019 Cheers mate. If you would Email the Australian Govt and advise them of this great gas saving idea I would be forever grateful :-)
Clean the inside of the glove box for the customer. If you noticed dirt from the old filter fell into the glove box.
1234yf will chronically over cool and freeze up when it's even just the tinyist bit low. Then just a bit lower than that, it stops cooling.
I grenaded the compressor on my chrysler 200 with 1234yf and I took the opportunity (since I was changing everything but the evap core) to change it over to r135. (Compressor and condenser kit was compatible with either refrigerant ) haven't had a problem since changing over.
Would it have been an extra charge to remove the dragon fly carcass? I would have paid it
Make sure leaves and bugs are cleaned from condenser. Noticed leaves when checking filter drier for leaks. I always wash the condensers when I see high sides above normal with low pressure water and cool cleaner.
FWIW, when I change cabin filters I always write date and milage on the new one, for the next guy
Ray, sometimes the condenser core being slightly restricted will cause a flood back condition in the TXV valve, where it surges with flashes of gas and the next minute liquid, giving a swooshing sound, I had to remove the front grill and radiator to find a really dirty condenser, clogged with a frigen napkin that had glued its self to the back side on the condenser core, the only way I could get to it is to separate the radiator and A/C condenser, clean all the Bull shit out and use coil cleaner. That frigen car drove me nuts for 3-4 hours. I feel your pain with the 1234YF, it's just like the days (1990-1991) we first got introduced to "Puron" R-410A I was a master HVACR tech for 40 years, and we went from R-22 with 60-65 PSIG low side and high side of 270 to 295 being normal, to this new Bull Shit R-410A Low side being 102 -145 and high side of 450 to as high as 800 PSIG, I can tell you if you have a leak with that high of pressers it whistles like crazy and don't even use your hands to find a leak you could come back with a finger missing. lol and PS: 1234YF is very very sensitive to just the slightest amount of refrigerant loss or an overcharge condition.
Every thirty minuet job is 1 broken bolt away from a 3 day ordeal.
Quick note: wow $1,000 tank and wow you have a roll up door. Right on it’s coming together. Did you put that last employer out of business yet?? I’m sure you will.😇👍🏼
Yes, the whole chain went out of business or should I say sold the business. New name and everything!

Still cannot get use to you guys in the States not having to stop at Red lights when turning right lol. Unless there is a sign to say "left Trun allowed after stopping" here in Australia, You would be up for loss of points and a hefty fine ($433 in my state).
Agreed, i'm in South Australia, i was thinking the same.
In Pennsylvania, right turn on red, and the left turn on red onto a one-way street has been the law since January 1, 1977. Intersections where it's not permitted are marked with "No Turn On Red" signs. Some are "no turn on red between the hours of X and Y".
A few local police chiefs were indignant about the change. The chief of the Duquesne, Pennsylvania police department huffed "I wasn't consulted about this!" and hung "No Turn" signs at every intersection.
The current problem comes from drivers who only marginally slow down and sometimes stop for a car or larger vehicle. This causes problems for pedestrians and cyclists.
It’s not as simple as your making it., most intersections require you to come to a complete stop and are allowed to turn right ( or left ) if the lane is clear. Some areas it’s required that you have to wait on a green light. Some intersections you again a lane with turning right and the directions tell you to keep moving. It just depends on traffic patterns.
In most US states, you must come to a complete stop before making a turn on a red light. Now if you have to cross over lanes of traffic like on a left turn (Or right turn in Australia) you can not turn on a red light. The fines for not stopping on a right turn without stopping are not anywhere close to what you are paying. That’s one of the reasons why the police say they add on extra tickets when they can
That’s why NO ONE in their right mind would want to live in Australia. Too many silly, unnecessary rules.
I curse those who think that 12-34 is 'better' for 'reasons'. Just costs everyone more time and money. I hear some people convert the systems back to 134a once a fault/failure happens.
When i saw the price on 1234yf i said F that, bought the fittings for my gauge set, and filled my truck with 134a.
Obviously you can't do that as a tech, but i have a feeling they created this new system to A: make money since it's patented.. and B: introduce the extensive leak check process by forcing people to buy new AC machines that comply with the new environmental standards.
R-152a works even better once you’re making substitutions.
1234 YF is just one more reason that I will not drive a new vehicle
My Tacoma had the same symptoms. I traced it down to the expansion valve. Expansion valve had a temperature bulb on it which regulates by ambient temp. People miss it cause its normally hidden. Pull up schematic of system and see if it has one.
I find it hard to believe that a Toyota experienced any issues whatsoever!
According to Scotty Kilmer and his minions, Toyotas NEVER experience issues. They only require an occasional oil change and windshield washer fluid top-up to last indefinitely.
As long as you perform the recommended $2500 services every couple years, they will last indefinitely. We just bought a 2021 Camry with 60k. It’s pushing 70k now and it’s already had $1800 in repairs (at the dealer’s expense thankfully). I haven’t put $1800 in my Mazda in 10 years.
I hear the same things about BMW and their “reliability”. (Not from Scotty, but from those most reliable studies). As long as you change every single part and every single fluid to BMW’s exact specifications, they’re quite reliable. If you half-ass it, you might as well get a second mortgage to buy your mechanic a new boat. At least with a ford, if I go a thousand miles over on an oil change and use Walmart oil, it’ll still be ok. It’s like BMW, Honda, Toyota and the like design their cars to be maintained exactly like the manual (I know we all should, but that’s not always possible) while ford and GM know that you’re gonna be a B- at best and design theirs accordingly.
@@williamegler8771 I mean there's a video titled: "Here's Why New Cars Like Toyota and Honda are Crap" by him, so....
@@williamegler8771 Truck was 13 years old and that`s the only issue had of the truck, every vehicle will break at some point but what milage. 2000 Tacoma owned 13 only issues expansion valve. 2013 owned 9 years zero issues. beat that dodge lol
@@stevewhiting556 Ford right now admitted they got quality issues, and they are forming a group to fix their quality issues. They had 8 million vehicles on recall in 2022. Research search it you will find it on the internet. As a Airplane and car technician for over 35 years I`ve delt with numerous manufactures and seen which ones i see the most. Every manufacture got their group of cars that last. I will say never buy a dodge. Repairs and depreciation value will make you go to the doc for depression.
Wow that is crazy low on refrigerant suprised it was cooling so well with that low of a charge at around 40 Degrees even at 55 degrees thats good cooling for such a small freon charge 😳 @Rainman Ray's Repairs
I feel your pain, for 1234YF I just use a simple Guage set and vacuum pump with the 1234 couplers. It is much much faster.
That's what I was thinking...with that machine, just go old school.
Had me confused, you said machine recovered 2.35 lb, display looked like 0.235, don't know how it would run and not shut down, great vids as always
the replacement cabin air filter had a lot fewer pleats than the GM filter, so less filtering area and maybe not as good a filter?
That can go a couple of ways. More pleats will also restrict some airflow and thus be a little less efficient. After all, you’re filtering HVAC air, not engine oil. I wouldn’t sweat it too much. I’m just guessing, but you can probably replace that filter 3 times for the cost of a genuine GM filter and it’s a relative non-factor.
300 or above PSI is not really acceptable even under those temperatures, I myself would go right to the expansion valve and see if it's faulty as this can raise the pressure considerably
I thought they were going for less head pressure with the new freon since r134a was robbing alot of HP from smaller engines. R12 was still the best refrigerant, it's funny how nothing was said about the railroad using R12 to clean tank cars. Happy 4th of July
They use to us r12 to wash airliners,my still use it
No, it was supposed to be more "environmentally friendly" than r134a. R12 works wonderfully. Used to have an old Nissan that used it, had wonderful cold AC. My current 79 Subaru has no AC at all, but it's small enough that it really doesn't matter with the windows open, and I like the simplicity. My friend has an 82 Oldsmobile Toronado diesel that was originally R12, but was converted at some point, still cools excellent, even with 134a. R152a (computer duster) is a better choice for retrofitting R12 systems than R134a. Cools much better with the lower pressures and is insanely cheap. You can get a tool that punctures the side of the can to extract it. In a diesel vehicle where you're not so concerned about refrigerant flammability, Red-Tek is an even better R-12 retrofit. Works with the original oil, and might even cool better than R12 did. But I wouldn't use it in a vehicle with a spark ignition engine.
If it were my car and found that R1234YF was 150 dollars the lb I would just try out R134A in it. Manufacturers aren't going to design a new compressor for the air conditioning system.
R1234YF uses the same oil that R134A does and they run within a 2-5 psig difference at the same temperature. There's no reason why you couldn't put R134A in.
I mean, R1234YF is 134A's replacement...
Ray try to clean ac condenser radiator with pressure cleaner mybe is full of dirt and insects etcétera
If you want your interior ruined then take it to this mechanic, he has no respect for his clients' interiors of their cars he's very hard on them.
I have had older cars where if they were on automatic temperature control, that the fan would slow down and the temp may change to maintain the ambient cabin temperature.
I hate the tap shifter! Each manufacturer that uses them has them work differently. I would rather have a standard shifter that marks off if it is in gear. If the gear is missing, then you know there is a problem.
We are the government.
And we're here to help.
For a thousand dollars.
They had an extra screw in the vehicle assembly kit so it was decided to put it in the cabin filter cover to hide the evidence.
Engineers are some of smartest people who design incredibly stupid locations.
Good video as always @Rainman Ray's Repairs
