2001 cavalier air conditioner blowing hot air

I have replaced the evap and schrader valve and cap. Chevy dealer told me that my compressor needs to be replaced and they want 900 to replace it. When we charge it the air is cold for 24 hours or so and then it blows hot again.

    This might sound like a dumb question but did you check fuses. I had that problem with my 2000 F-150 5.4L. The A/C wasn't blowing cold. I charged it and it started blowing cold but only for a day. I assumed it had a leak then I found later that a fuse had been moved. I guess it was checked, then put back in the wrong spot. That fixed my problem. You could check that. Other than that is sound like a leak.

Why do they want to replace the compressor?noisy?If you can put a charge on the ac then it's hot again after a day,then you have a leak.all the ac lines have o-rings where they are connected.without put dye in the system you wont know for sure.So I would try that first.

How to fix air conditioner in 1985 toyota hiace


My 1986 would leak. The HP and LP hose coonections to the compressor where lose. Tightened up and stopped most leaking. I added leak detector and found the LP fill connection Schrader valve seat was bad. Put in a new Schrader valve (bought off ebay for cheap- but a couple of extras) and all leaks stopped. Night not be compressor itself. Have a pro check the system for leaks.

History?was it working before? you cant just hook up a hose and put it in. First find out why compressor wont run, If it needs compressor, it needs a drier and orifice tube, put on a vaccuum pump for 1 hr then recharged with the correct amount of r134. You need someone who knows a/c to look at it.

2001 Chevy Suburban rear a/c warm front ice cold


I believe there is a expansion valve located on the back part of the air conditioner on the back right side i believe that could be the problem. I think if I am understanding you correctly, your back air is not as cool as it should be or not cold at all. Might want to check this. If I am not understanding you correctly please let me know again what your problem is.

Have a 1986 F-350 A/C puts out cool air but not cold. Don't know if system is R12 or 134A. Compressor is centr and has 2 threaded black caps with schrader valves for gage connection plus 1 quick disconnect...


in 1986 it is r12 but you can convert to r134 which is a ton cheaper than paying for r12 you need a license to buy r12 r134 is right on the shelf at auto zone they also sell retro fit kits with everything you need to convert your system and they work very well

1999 Chevy Cavalier A/C blows hot air


More likely the recharge blew a o-ring and you have a leak. When your Cavalier was blowing hot air and a recharge fixed it that means it was low on freon which lets o-rings dry out, go back to the shop and have them leak test it. They use a pressurized dye to find the problem. If it's blowing it's not the cooling fan relay, they may have meant compressor relay but I'd have a leak test done first it's not expensive and easier that chasing unknown possibilities.
