Yukon a/c blows hot air


Assuming you hear some kind of clicking noise when you turn the AC on (the compressor clicking on):
Seals on the AC compressor likely bit the dust. GM AC compressors go out almost as frequently as tires. The good thing is that they're not horrifically difficult to replace. You can get some freon with dye in it at your local parts house. Get enough to fill it up as though it's empty (as it likely is), and see if it starts blowing cold. It should blow cold for a little while (days/weeks maybe), but when you open the hood, you'll notice some green dye around the compressor. That's where the seals have failed and why you get to be the proud new owner of a brand new compressor (don't waste your time on a used one from a salvage yard. You'll get to replace it again soon, if you do.)

Nissan sentra ac blows warm and cold air


Usually low on freon or a faulty pressure switch.
Could also be a problem with the ac clutch on the compressor.

2005 pathfinder, ac has stopped blowing cold, and it shudders violently when the compressor tries to come on. Not sure where the problem is in the system, but it will blow cold for a few seconds, but then...


Hi and welcome to FixYa, I am Kelly. The symptom your describing sounds like the actual compressor pump take a lot of horsepower to turn it. Use a ratchet and socket on the center mounting nut for the compressor clutch. I would just about bet that it is VERY hard to turn. It should turn through with minimal resistance. If it is VERY hard to turn the compressor has failed. I would like to know either way on how hard or easy the compressor clutch mounting bolt turned. Just make sure you rotate the pump in the direction it would be turned while the engine is running.

2003 chevy s10 - keeps blowing out AC fuse. Will work for a couple minutes then compressor quits working. Check the fuse, it is blown out. Put in a new fuse, works a couple minutes, then quits, fuse blown...


Unplug the a/c compressor, there will be a plug near the pulley. Install a new fuse. Start the vehicle and turn the a/c on. Wait about the same amount of time it took for the fuse to blow in the past. Did the cues blow? If no replace the a/c compressor, the clutch has gone bad. If yes, than the wiring between the fuse and the relay or the relay to the comps sore is grounded. A careful inspection of the wiring should reveal the problem.

01 Sebring convertible, AC was low on refrigerant, and would stop blowing cold air and start blowing warm air. I added refrigerant, and it worked perfectly for about 20 days. Now it blows cold, then it...


First of all if your system was low on refrigerant there is a leak.You can recharge and exspect the air to work,how long it will last depends on the size of the leak.Somtimes the refrigerant can have a leak prevenative but this is for very small leaks.You need to have dye put in to system and use black light to find leak.they make kits at your local auto parts store that you can buy and do this your self.If you say it worked well for about 20 days, that is a fairly large leak.The reason why the compressor is acting so erractic is because the freon has oil in it and lubracates the bearings in compressor.When the system goes low the compressor will turn on and off to protect itself.Eventually it will stop running completly.Idont think you have an electrical problem,Ithink you have a big leak.Try what I said and good luck....Brian

It will take it a while ,until the compressor starts staying engaged long enough to **** the freon in faster.
