My GM was doing the same thing, pressure switch was going bad. $13 at Oreilly. I diagnosed it with my $0 hand scan tool, I wiggled it and got it to replicate the problem.
13:23 just about anyone can replace an AC compressor, alternator, starter, etc. Getting the correct diagnosis in the first place is a different story, this is what I am here for. Excellent! Thanks for the tips and tricks.
Yea, thats most likely why there is 300k on it originally! I'm here solving the same issue though I'm only at 225k on my 2000 Silverado, replaced the switch on the dryer already since it was original and didn't cost but $20. My problem still exists though and it quits blowing cold and doesn't get cold again unless i shut truck off and it resets system!
Sometimes they’ll do that when the clutch gap has become too large from wear. Most of those Chevy trucks you can get some more life out of the compressor if you take off the front plate on the clutch and remove the spacer behind it. You can do it without removing the compressor too.
@@WizzRacing there is no way to know that without testing it while it was failing. The magnet gets weaker with heat and when the compressor cycles off and back on its not strong enough to close the gap. A bump or vibration can give it the little extra help it needs. To say definitely that they could windings failed when hot when they were never tested under the failed condition is pure speculation. It happens but I’ve had dozens of these trucks over the years in the shop fail this way and I’ve help customers who couldn’t afford getting the compressor replaced get by with just setting the gap on the clutch.
@@Jpilgrim30 You can test the coil. Just put an ohm meter on it.. And no setting the Air Gap does not fix it..As it uses a washer. If the Clutch is wore down that far. It needs to get replaced anyways. So why waste all that Freon. Time and Labor. To only have it come back for a failed Clutch.. Just replace the whole unit..
Finally, a video that pertains to my issue... somewhat. My AC sometimes works. And sometimes it blows "cool" but not cold. Now I'm starting to think its the compressor clutch, especially with 282,000 miles.
I had this issue in a 2005 chevy silverado. One of the radiator fan relays had a poor connection. So driving the ac would turn off from regular bumps or stop and go. When the ac is on both fans should be on or on another car something easy to check. Press down on the relays see if one or both fans come on with ac on
Damn. 300,000+ miles on Chevy compressor! They just don't build them like they used to! You absolutely wont find a newer Chevy that will last that long. Ive replaced several that took a turn south before even making it to 100,000. Nice diag. That's exactly how I would have done it. Love the channel!
Great video! I just the A/C components in my 2002 GMC Sierra 1500HD SLE Crewcab. Had the system vacuumed/recharged before and after removing/replacing the A/C parts. Passed the leak test as well. The issue I have is with the A/C condenser fan that short cycles. Can you tell why it does that and how to fix it?
Very insightful on the Intermittent problem. Have a 06 Chevy Silverado that has just begun with this intermittent on/ off crapola 😡🤬 guess it’s time to visit my own mechanic extrodinaire 🤬
You are the Man! That's exactly what's happening to my 2014 Chevy Express van. But my fan turns completely off for about 10 to 15 seconds. Then blast back on 🤔
Great video, Eric! In my experience, buying a complete compressor (with AC clutch coil) is almost the same price as buying just the coil itself. Doesn't really make much sense nowadays to not replace the compressor itself.
Intermittent failing clutch is diagnosed with amp probe in addition to things that were verified on this vehicle. The clutch gap was wide on the compressor as it was visible when he showed the old compressor. Wide clutch gap would still give amp draw of 2.5-4.5 A where failed mag winding would drop amperage to 0. If you don’t have amp probe you let it quit cooling and the safely tap clutch plate to see if bumping it allows engagement. With wide gap the reduced strength of hotter winding is too weak to pull clutch plate into pulley plate and the bump will do it. Windings can have a short (very rare) and do the initial function and then quit but usually these blow a fuse as the current draw goes up. With 300 K miles a new compressor was a good idea anyway.
got the same truck, would have loved to see what lowside pressure you ended up when all was added ias as i have to do a similar job on my truck. i know it is realated to outside temp but I always struggle with the pressures.
You pull a vacuum to empty the lines of Air / Oxygen & Moisture / Humidity so the Refrigerant (Freon) is more efficient and the AC cools better. After pulling the vacuum shut the valves and make sure the needles hold steady ( 20 minutes) to verify there are no leaks before charging the system. Finally, purge the air in the supply line before releasing the Freon into the system.
Front brakes, 4 struts, compressor and some other AC components all in a day? Hats off to you, that’s a lot of work! Were those complete struts or just the struts themselves?
Man thank you so much bro this is exactly what going on with my truck bro I've been taking it to a couple of people and the tell me different things. Thank again man
Thanks for the video. I have a 2006 GMC Sierra 2500 with a 6.0. A/C works good as long as your running. Then if I stop for a series of traffic lights it starts to blow out warm air. Cost wise what do you guys get for a job like you did parts and labor?
Very good diag. Intermittents can be a p.i.t.a., especially when they're extremely intermittent. Putting the system under load helps to locate it more quickly like you did. Hot weather helps also. You had the shop recover the freon. Did they put it in a container for you to reuse, or did you give it to the shop and you used new freon?
I had something similar happen with my 2001 Chevy Silverado Ext Cab 4x4 Z71, I left my truck idling with A/C on and went into store and came out 10-15 minutes later it was blowing HOT air out the vents and the interior temp was extremely high inside the truck, even with the A/C still suppose to be on, however the A/C never stops working while truck is moving and is cold as hell...?
What he was trying to say is that before you break the lines lose rather than releasing the Freon into the Atmosphere go to a bigger shop that has the special equipment that can recover and recycle the Freon to protect the OZONE layer and also comply with EPA Rules. That is was a Pro A/C mechanic does.
Ozone layer is milarky bud. Same way they want powers to govern over medical emergency is the same plot to take our freedoms and not give them back under the guise of climate, it's all bullshit they are just priming you to take the bait before they even throw it😂
Just a fyi, you can remove the clutch shoe from the pulley by removing the center bolt and remove a shim or two to reduce the amount of air gap between the shoe and the pulley and it will continue to work for a long time until wear creates another large air gap. When we had these come into the shop, we would bump the front of the shoe with a long pry bar while running to see if it would engage from the magnetic coil to prove if it was just too much air gap due to wear. Quick and easy fix.
You can also find the cause with the ac compressor clutch. If it has a field coil that opens within itself, there may be an updated field coil to solve the issue. You could check service bulletins and find the part number that stays fixed and doesn't fail again. Two ways to look at it. When it's an aged system, the improver coil may be in the parts kit and save money by not having a later failure unrelated to this repair. A lower mileage truck with warranty would just need the field coil. That how they would be required to approach it in most cases. No interruption to the system, just the engagement being corrected.
hello there i have Issus with my car ac system its chevy impala 2015 when ever i hit 80 km in hours all or sudden my fans stop working and ac also cut off and never work again unless i press ac button off and on again,,, i have vacuum the system and change the ac control valve then recharge with right amount 680g r134 but same Issus still there
I replaced my clutch coil.. it engaged after I installed it.. the next day I started the car and the clutch would not engage.. also the fan connected to the pressure switch.. will a loss of pressure keep these components from working.. I suspect low pressure via leak?
Have a similar problem 04 silverado. A/C comes on drive a few miles then HOT air blows from the 2 drivers side vents but the passenger side vents stay cold. Shut the trk down & restart it works fine ??
I have a 2015 Yukon SLT that I changed the evaporator core and fan blower.Now suddenly it started to blow hot air .I parked it and turn it off for 4 hrs and turn back on and now is working
I thought that the compressors would kick off if they were just low on free on as well my on as well. mind did the same thing I just put more freon in it & I didn't have to replace the compressor luckily.
Do you think this can be causing my door blend actuators not to get any power at all ? My truck only blows warm air no cold at all it’s an 03 Silverado 1500
Why did you remove fender liner / under the truck etc? I just did the same job and never did that.. I took it all out the top. I got the bolts loose, connector plugs and removed from the top, no under truck necessary. I did have to swap the sensor in the rear of the compressor, the aftermarket one did not have the sensor. Good job though.
Question, my 2004 1500 ac push button switch on the dash seems not work, weather it shows on or off, "it it is always on"...... The ac gets very cold down to 39 degrees, but sometimes it will not reach 39 degrees and will stay around 48 degrees. If I jump the pressure switch connector it immediately goes down to 39 degrees. When the pressure switch is connected it sometimes will go down to 39 degrees and sometimes not. My question is do you think I have a bad pressure switch and I'm not sure why the dash button will not turn on or off the ac... it just stays on. PS it is not the blend doors causing it to go hot or cold.
Hello,, I'm little perplexed.. I am currently looking to help a neighbor with his Chevy Sub 1500LS A/C.. and I was trying to find the two ports ar which the red and blue hoses connect to. I'm perplexed bcuz I am seeing your red hose connected to "the coolant reservoir??? Is that the location? I can't seem to find it. Can you explain where the high side port is? Thx.
I have a question! I Have a 2004 Chevy tahoe 4.8L my ac doesnt work, but even when the ac is off still blowing hot air, and when is on ac is only blowing HOT AIR, i replace the the pressure switch , i replace the actuator under passenger side( was a pain in the rear) , but nothing is fixing it i can see the compressor click on but not stay on, starts but stops right away WHAT DO YOU THINK? COMPRESSOR MIGHT BE BAD?
Wait, you took this truck out on two separate drive trials trying to diagnose the AC and you didn't discover that the rotors were warped until you took off the wheels? I've never discovered warped rotors by looking at them.
"really warped" rotors - would of felt pulsating in the brake pedal, shake in steering wheel, or both. All that money into the thing and check engine light still on. Car shield would tell you your heading towards more serious problems than the A/C not working properly.
Eric, when did you record this? The tag sticker on the window shows 2014. Are the tags that old? Good vid, again. Good process figuring out the issue. 🤘
I was having this problem, the low pressure line would freeze over and you’d see ice all over it when the ac was in 1-2 setting. But, if you put it to 5, it would defrost and then blow cold again.
Hey brother I have a issues with both of my truck doing the same thing except they both have new radiatior condenser dryer and compressors also replaced cabin filter and it’s still doing the same thing turning off it flashes the light on the ac control ? Any ideas?
Why does the AC cooling goes down while tahoe is at very low speed or in nutral? Is there to deal with it? In Dubai its very very hot in summer, with a black tahoe, i avoid driving her in day time un summer and use my sequoia instead!
Hi I have a problem with a Chevy equinox 15 get cold when they start but later on blows hot and air compressor is on I noticed I feel the line it's really cold and then stop running the freon any idea?
I’m working on a 2000 GMC Sierra that cycles from cold at idle and compressor kicks off when I’m driving causing air to get warm. I replaced the compressor, cycling switch, accumulator and orifice and the problem is still there. So I flushed the evaporator and installed a different 17mm orifice and it’s still doing the same thing. Any ideas?
My 2006 GMC Sierra still has an intermittant A/C loss. Dealership can not find problem, other shops say it works fine. I have seen where it stops cooling after my dash volt meter drops below 13.5 volts. I can turn headlights on -alternator starts charging and at 14 volts A/C starts cooling again. How do I fix this -already had new battery & alternator.
when engine hot ; breaking and AC off itself.. after its on and again when ı pressed break off itself.. Compressor is new and no leaks. Ground pr pressure sensor problem ?
So i just replaced my ac clutch and it is still turning on and of. Would I replace my pressure sensor? It's failing and giving the computer a false signal?
I have 03 silverado 240k miles.. My AC cools fine when I'm driving. However when I'm idling at a light or stalled traffic all I get is HOT outside air.
Was good Eric I have a problem . my 09 altima 2.5 . i have a p0335 . i check the ckp malfunction and did all the electric first and no signal ckp then i took the ckp out and the middle pin was bend so i thud that was the problem. So change it .reset the light but the light went off and came back but the second time is off .so the question is do i have to do a relearn on this 🙏🙏🙏🙏
Way better video than most. You speak fluently without a lot of ers and ums. Thank you.

fire the parts cannon
You gotta love customers that understand the importance of getting other work done when it's there and apart at your fingertips.

This isn't a duct actuator issue is it?@@randydarby2340
Like Ivan @ PHAD always says, you have to be 110% sure before replacing parts. Good job Eric in proving the problem.
Yup, just like Eric O at SMA. These pros rarely fire the parts cannon.
Bro said it was the clutch and then replaced the whole compressor, etc ,etc… seems unnecessary.
Great concise video that explained why my 2004 GMC Sierra A/C would stop blowing cold air. THANK YOU!

See EricO at South Main Auto how to test and then repair the clutch.
Setting the Air Gap would not have fixed this issue. As it did work. The Coil was simply breaking down once it got hot..

The magnet gets weaker with heat and when the compressor cycles off and back on its not strong enough to close the gap. A bump or vibration can give it the little extra help it needs.

331k miles on the odo is what impressed me.
Sometimes its the thermal fuse link inside the clutch coil that gives you this problem , good to see you up getting back on it again
The corridors part was so funny lmfaoo keep up the good work !

Super helpful video i have the same truck same problem 👍 Ty
1yr old compressor
no leaks

I've had this problem with compressors like this, you snap the gas wot and the compressor kicks in again. why ? Great diagnosis.
Most ac systems are designed to disengage the clutch during WOT
@@barstadryan Honda does that as well save the hp on WOT
You pull a vacuum to empty the lines of Air / Oxygen & Moisture / Humidity so the Refrigerant (Freon) is more efficient and the AC cools better.

Once you crack the lines the pressure AND the vacuum are lost - So how is it that you can replace the compressor without losing your vacuum?
Hi eric i have a question for you . how did you flush the AC lines make a video thank you
Summer is here baby🔥
What he was trying to say is that before you break the lines lose rather than releasing the Freon into the Atmosphere go to a bigger shop that has the special equipment that can recover and recycle the Freon to protect the OZONE layer and also comply with EPA Rules.

Where are you located? I'm having the exact same problem.
when engine hot ; breaking and AC off itself.. after its on and again when ı pressed break off itself.. Compressor is new and no leaks. Ground pr pressure sensor problem ?
So i just replaced my ac clutch and it is still turning on and of. Would I replace my pressure sensor? It's failing and giving the computer a false signal?
I have 03 silverado 240k miles.. My AC cools fine when I'm driving. However when I'm idling at a light or stalled traffic all I get is HOT outside air.
Amazing video man keep them coming 👍
