Hey scotty is a 2007 2.4 eclipse a reliable car ?
hi Scotty, I live in phoenix AZ we are like 110° degrees already 😣 I missed your live couple days ago.. I'm having A C problems with a 2006 grand cherokee 4.7. I've taken it to a couple mechanics but they all have different problems. one can't find a leak, there's no hissing and can't find a leak anywhere. the other 2 mechanics said that it's the discharge hose because it looses like 70 pounds of pressure in a couple of seconds. you can see like oil residue on the hose.. any opinions would be greatly appreciated Scotty..
Scotty Kilmer key replacement
Scotty Kilmer my AC blows hot air when i am stuck in traffic,not moving. But after i step on my gas,compressor will turn on again.
Scotty Kilmer , Hi Scotty my name is Shirley Norris. My question is about my car's A/C. It blows cold when my car is going, but stuck in traffic my car blows hot air. What's wrong?? Help!
1:55 haha when he said the compressor was leaking I thought he held up a cup of beer to say "well dang, that's really too bad"
😂😂😂😂
I was thinking it was a beer break
check the connection at the end of the compressor, the wire that plugs into the compressor clutch may have come loose
if you don't do it yourself, call around for prices and PRAY you find an honest mechanic who knows what he's doing. I started fixing em myself cause I can't stand paying money to people who often know nothing about what they're doing.
yeahhhh, I'll let a professional do this one for me.
lol me too
cameron brown have fun spending a arm or a leg.
@@venividivici4253 Have fun minding your own business
yea for sure he makes it sound so easy im wondering if he's talking to regular people or people with a good knowledge of mechanics buy this n buy that then what do you do with all those tools n equipment ???????
@@MrTarkus007 it's actually not as difficult as you think. I started tinkering more with my car and truck after years of taking them in for service. RUclips and various forums are a great way to learn.
The hardest part is diagnosing the problem like Scotty shows here. Sure, you're gonna need some tools, but that's to be expected. Compare the investment into some tools to a few shop visits. It's a no brainer.
A few years later, I've swapped alternators, power steering pumps, wheel bearings, lots of rotors and calipers, and the list goes on. Most things are very simple to change, it's just figuring out what's actually broken.
Scotty Kilmer is like the MD for cars!! I really look up to him!!
Thanks for the support👍
Mandell Hosea i know right
Always check your AC compressor relay as well before you get too involved. Solved my issue by simply replacing it
Scotty is the natural born mechanic/technician...if ever I saw one...and obviously a most likable guy if ever you saw one...clear and smart on every tutorial.
👍👍👍👍👍👍👍👍👍👍👍👍👍

Scotty is an honest mechanic, hard to find.
I have been watching all of your videos whether I need them at the present time or not. Knowledge is power, right? As of now, I am currently DRIVING and restoring a 1996 Jeep Grand Cherokee 4X4 and my newest project, a 2001 VW Beetle. Both are running so my problems are not pressing issues at this time but I appreciate your videos mostly because you seem like a dork (like me) and your "easy fixes" have already saved me time and money. Thanks for all of your time. Good luck.

Scotty Kilmer Right now I'm working on 2 rebuild/restoration projects....I have a 1996 Jeep Grand Cherokee Laredo 4X4 and my wife's new love which is a 2001 Gecko Green VW Beetle. Your video's have already changed my mind on how I'm going to repair some of my issues and I'm sure your shows and new videos will help out even more. Luckily for me, both cars run at the moment...You have been a lifesaver so far, Scotty! Thanks again. Good luck.
SCOTTY IS AWESOME!!! I've learned how to solve every single problem for the past two years from him.
I love the flavor in these videos. Too many DIYs are too long and awkward and all the facts are drowned out. This screams experience.
you can try adding some, pray it's just low. but you really need high and low gauges hooked up to analyze it correctly
Scotty knows cars he fixed all my cars without touching them I watched his video when I needed something fixed that's how hes a virtual mechanic
Just wanted to say I'm new to taking care of cars and your videos have been very helpful. And the fact that you take the time to answer every question you can personally is also amazing!
if it's in the red zone, NEVER add more refrigerant that just makes it worse. Pressure build up is often internal ac restrictions that require taking the system apart to flush and repair the restriction
Thank you Mr. Kilmer for sharing your knowledge. These videos are very helpful and greatly appreciated...
just replacing the compressor is often a no no. they normally break because something else is wrong in the system, like a clogged condenser on that model which is common. Have any good ac guy hook up gauges and analyze the pressures.
Scotty is great! Love all of his videos and he has taught me so much. Just they type of guy you'd like to work with in a shop to learn all the tricks of the trade!

"Now we got nice cold air blowing in the face!" Love it!
are these all your cars or do people take their cars for you to fix? love the videos, by the way, they've helped me save a small fortune
I've been a pro mechanic for the last 48 years, they are other peoples' cars
Scotty Kilmer did a rebuilt a/c compressor bite you in the rear end
nbarrager Productions hey Scotty my ac is blowing hot air in my ram 1500 2009.conpressor and clutch is working fine also . My question is do I need to evacuate the system to add Freon or can I just go ahead and add more
@@topprotips5250 evacuate system always first. Pull a vacuum on it for around 1 hour to make sure you get all the moisture and contaminants out of the system then weigh the charge in using a refrigerant scale.
Now if it were only this easy.
lol almost never is
Lol
It is
Hey I know that is a 84 or85 Celica Supra. Loved those cars a lady killed my 84 GTS last great cars Toyota built! Then they went way left and made no sense to me at all but my wife had three Camry’s hated them my self. Nice to see someone cares for these cars.
Scotty nice to meet you! I'm Elliott are you located in Southern California by any chance? so maybe I can bring my car to your shop for you to fix it . You seem to have a lot of knowledge & experience and you're fun & genuine you have a great sense of humor wish I can have a mechanic like you to worry less about my car
I was kinda alright up until you took the compressor out. Now I’m like, “I’m good, I’ll pay someone else a some $$$ I don’t got to do it
Scotty my man you make it look like you have done this a time or two. It's a Sunday morning as I write this to you. I pull in to Firestone Complete Auto Care. First in line and ready to pay way to much. The manager tells me his AC guy is off on Sundays and Mondays!!! How the heck can you be a national chain fix it shop and not have an AC expert there if your business is open!
Your enthusiasm is the best 😂🥰
Hi Scott!! My 02 cavalier blows cool air when driving but when stopped it blows hot air. Is that a sign of a bad compressor or bad pressure?

Hi - A/C in my 1999 E320 keeps running after I turn of the ignition. I tried to figure out which fuse controlled it but could not. I had to disconnect the battery so it would not die. Will keep doing this until I figure out what the problem is. Any suggestions as to why this is happening and how to fix it would be appreciated!
Scotty is the best and has the best repair videos

Hey, what does it point to if the a/c blows cold when the car is moving but warm when idling?
I’m having the same problem
you are low on freon get a diy kit and fill it up.
Mine is almost the opposite. It blows scorching hot air when the rpms are high and blows cool AC air at night abd idling.
Jeremy K my radiator fans were backwards 🙄🤷🏾♀️
Thanks, Scotty. Perfectly understandable directions. You ROCK!

This guy's my favorite RUclips car guy
On today's edition of 'Where are they now?' Commander Data
Good One! LMFAO
Thanks, I've been trying to think for ages who he reminded me of!
Are you using propane for refrigerant...? Or, did you buy it in a larger quantity...?
BigRed56 mechanics like myself use 30 pound cannisters of R134a cause it costs tons less that way
Scotty Kilmer
Reduce, re-use, recycle.
I have a 00 Ford ranger n the AC clutch clicks on n off every few seconds.. is that normal?
even with heater too
sometimes it is. I had one car that did but there was no problems with ac system so I assumed that was normal. Besides, its the pressure switch's job to shut off the compressor
That normally indicates a low charge.
it's leaking, so find the leak. Put UV leak dye in and see where the green comes out.
Hi! I have an 01 Civic. The A/C worked good. (I use it often) Then suddenly the next day. It stopped engaging all together. The A/C light stays on, but clutch is not engaging. Both fans at radiator do turn on. BUT however, the compressor was very noisy before. But had no effect on cooling. The noise did stop about a month ago. And worked good til now. THANKS
Hey Scotty firstly I want to thank you for your time and help saving money on our cars I wish I know all you know about cars but I m learning more watching a lot of your videos thanks again . I been trying to get an answer when you are in youtube live but I don't get my answer, 99cadillac seville passenger side is blowing cold air and the driver side blows warm I think is the actuator and code
wow the amount of illegal A/c techniques in this video are amazing
lawyers have taken over the world. But here in Texas, most people don't care.
Yuuup!!
I saw people they add PAG oil on accumulator/drier. Doesn't hurt the system if it's too much oil. Thanks again
expansion valves can go bad, condensers can clog up, and if a modern car, see my video "Fixing modern car air conditioners". Because modern ones are all computer driven and hundreds of electronic things can go wrong on those.
Great clip, you need your own TV show! Now to figure out my own problem, of warm air from AC in my 08 Ford E250.
Nice video! You made me feel like I could go out and do this myself lol.
His videos always crack me up at the end of his when he appears and is hiding in his rear ends 😆
really enjoy watching his videos, just to pass the time.. lots of information
should have replaced the expansion valve too, that's a biggie for cold honda air. same process for all refrigerants really, only the actual pressures differ
love the old scotty content lol
Thanks you showed people how to do it more the correct way instead of just dumping a can of R134A into the system blindly.
Thanks for video. It was very helpful in my repair. You saved me hundreds of dollars.
I like these older videos. Before the fame😉
this guy is great he should have his own tv show
Shouty Scotty nailed it, again!👏
I’ve saved $100s on fixing my own cars. Just with a few simple maintenance tips from Scotty I’ve probably saved thousands.
Hey Scotty yeah my air was blowing nice and cold out here in DFW area. Then the car stopped on me and wouldn't start. Then I thought it was battery but two truck guy said, "it's full charged. Aint the battery." Then I saw your video about PCV Valve and the intake filter thing. I asked them to check it and air conditioner. But they said they did but I don't think they did. I was on frwy car went dead in traffic and started back up. They claimed they replaced the memory thing. Then today they said it was the air compressor that's causing the battery, and no power, gas to car. So They disconnected the air thing and told me the pulley or some belt was loose and could break at any moment,. I said just get it in writing. I would need to ask Scotty KILMER what he thinks is wrong and I will find a way to get it done on a GRAD students BUDGET in TEXAS. So far Scotty was right about the after market Ford SENSOR the same company wanted like 1800 for ONE Sensor. BUt i was like NOT.. let me talk to the forum and see what they suggest. So far my car has been GREAT. I keep it clean, oil changed, and I even put that stuff in it to GUARANTEE a pass on inspections you get a Walmarts. I found out about that on here and some other products. So If anyone knows how to go about getting best rate affordable for air conditon compressor. Let me know. I can't be riding in the heat. But I also know that somehow there can be a way to find someone here in my small town near FT WT. I wished I lived near Scotty. YOu are the BEST. Thanks so much for your awesome videos. I have so much fun watching these car mechanical videos. It's so much fun to sort of know what's wrong with car when you go.
pressure test the high and low side with gauges, and e mail me those pressures at idle and at 2000 rpms
They should call this dude the car guru
this guy help me so much whit all my cars thank you
Quick update... I meant 03 Corolla. Upon correctly searching 03 Corolla I determined there was a defective a/c relay in my make. Replaced the ac relay with the horn relay and like magic ac kicked in. I'll be hornless until my amazon purchase of $15 arrives next week.
Scotty, still appreciate the vids though!! :-)
man rich pin you are a life saving genuis may the lord Jesus bless you, have happy fathers day
you have a leak in the ac system, fix that first. That hot air is probably just the condenser fan blowing air around
Scotty Kilmer I have a 1996 ford ranger , I change the expansion valve and charge the system but still blowing hot air and the compressor works perfectly, do you think is the condenser, please help me .
Scotty'; Thank you..! you are "Holy Saint of Auto Mechanics"
THANKS for you reply! My A/C worked again! It was good all day long. Now it just stopped engaging again. It doesn't "click". That's the problem I been having. I don't hear a click or don;t see the clutch engaging. I feel like some switch or relay is bad?? Could that be right?
Many, many things were left out of this procedure. For starters, that compressor (a Denso 10PA), is one of the best around. Changing seals (shaft and body) will bring it back to life. You left the filter dryer out (no wonder why they'll come back to haunt you). You did not flush, and left all debris in. Vacuum is pulled from both sides. Those Robinair gauges, unless used, do not cost 50 bucks. 125 more likely. The only thing you are totally correct is about the rebuilt compressors.
First time car owner and you bn helping me so much Scotty thanks for your videos and I like how you try to entertain us :D keep up the good work

dam i have work at that time but if i get the chance i will thanks for your help
I inherited a truck that blows hot air constantly in a '04 Chevy Silverado. I replaced the actuator behind the radio because I was told to do so but the next actuator immediately to the right occasionally starts loudly ticking. My Uncle believes it is the compressor but I am still concerned about the ticking actuator and the other two under the dash.
That flash light had me looking like 🤯🤯🤯🤯
Scotty, I replaced the compressor, the dryer, the accumulator and recharged the system with the correct amount of refrigerant, the ac worked great for two days,now it once again blows hot air only, is this the blend door actuator, 2002 ford taurus pushrod engine?
08 VW Jetta - blowing warm air and low pressure was about 100. Lowered pressure and within normal ambient temp at this time. Fans were not working at the time but worked my way through the system and found the ECT sensor was bad. Changed that and fans work now but still blowing warm air. Compressor clutch appears to be engaged but couldn't get a voltage reading. Then if it is engaged why is it not blowing cold air. Low pressure around 50.
vws have one of the most complex computer run AC systems on the market, I've read hundreds of pages of technical issues with them. But, do the low and high pressure readings at idle, and at 2000 rpms, and give me that info
2:00 '"And now you'll just have to wait, I suggest you freshen up with a cold one, cheers! '' (guy's pops out a pint of really light beer).
often bad expansion valves do that
You're the man Scotty
I love this. I have learned so much but my car is toyota praius and for the past months I have been toping gas because the AC was not cooling well and two days now the AC is blowing very hot air. Please help as there no good repairer around.
I heard it might be one of the pressure switches, hi or low side, what do you think? im going today to buy some gauges. thanks
Scotty, Long time sunscriber and fellow Toyota fan here. The AC on my wife's 08 Kia Sportage V6 has been working some days and NOT AT ALL on other days. I took it tonthe dealer (on a day it wasnt working) and they said they couldnt get the compressor working at all. So they ordered one and quoted me 800 bucks. Now it is working again today! I wonder if there could be something else causing it to work intermittently and actually not need to replace the compressor? Thanks in advance if you should be able to see this and answer it.
Thank you scotty for the effort. But my ac works fine at night and bad at noontime heat here is 120f 😔
My car was blowing hot air, but it was not Compressor. It needed Freon. Now works like always before.
Hey Scotty, my 04 Solara starts out blowing cold, then the ac light starts blinking and blows hot. What is it? It’s killing me not having ac out in the desert.
Hi Scotty, I have a friend that owns a 2002 Honda Prelude and recently something went wrong with his AC. Whenever he turns it on, the car (engine, inside the car, everywhere) shakes violently and the air isn't as cool as it used to be anymore. He mentioned that he saw smoke coming out of some area under the hood of the car, but he wasn't sure where it was coming from. If you could help us out, that'd be great.
Thank you.
Do I check the pressure of the low side while the car is running or while it's off?
Can you do a video about how to fix the AC on a Harley?
WOW A TOYOTA Celica / Supra from '85! That must of been a joy to work on and drive :) Was it a straight gear or auto?
Would a leak be the culprit if your ac is blowing hot air when it's hot and cold air when the temp drops?
What about when need to take out refrigerant is that something that one can do?
Are you overcharged or looking to evacuate all the gas?
Metal Halide evácuate.
@@steven-sl7jv Best to have shop do an evac, should not be much, that machine is expensive, charging you can do.
I was informed that a compressor that clicks on and off rapidly is due to low freon. I checked the low pressure and it was good. What should I check next?
2004 F-150 V8
you have to check both low and high pressures. Clicking on and off is also often a restriction in the system, making high side pressure too high, then the computer turns it off
Thank for the response. Will take the advice.
*****
What do you think of the refrigerant cans with the gauges that they sell at Wal Mart or auto stores? They seem to work for some people. Can they damage a car? Is the stop leak stuff in these cans bad for the A/C system? Thanks in advance!
Thanks for this video. It's great and pretty entertaining. I just subscribed!

Nice video again Scotty. Why shops they always say to replace the accumulator and drier Chen you open the a/c system? For extra charge or something? Thanks
dan deac that's to be safe, as water vapor contaminates them. BUT, vacuuming a system for an hour or so will cause the moisture to evaporate out of the system, making that unnecessary
seems that way
that's a very pristine Supra you got there
Mr. Kilmer, I have always heard that venting to the atmosphere is prohibited. Aside from taking the car to an AC technician with the proper equipment, how does one capture and prevent the refrigerant from venting to the atmosphere? Thank you.
I have a 2002 Ram 1500 4.7l. My AC worked great, now it just quit. It shows almost 150 on the "AC PRO gauge( in the red). Fuses are good, and the fan is spinning. Could this be my compressor? Can a shop relieve/capture the over pressure? Thank you very much for any info given. Happy Fathers day.
