1994 chevy 1500 ac compresssor stopped working fuse is good


couple of reasons
there is no gas in the system and the low pressure switch has stopped the ac compressor
there is too much gas in the system and the high pressure switch has stopped the compressor
there is a blockage in the tx valve and the high pressure switch has stopped the compressor
The climate control module has failed and stopped the compressor
I am thinking a leak and no gas.

83 chevy 1500 ac compressor kicks on but no cold air


Without a manifold set to check pressures, the only thing to check is the blend door on the heater to see if it is stuck on heat.

First thing is have the AC charge checked by a shop, if that is OK then the AC compressor low side pressure switch may be defective or the compressor relay is defective.

2006 Chevy Silverado 1500 z71 4x4 the ac wont kick off after key is out of the ignition and it only blows hot air.


I am assuming you mean the blower will not stop with the key off.
The compressor can't run with the engine off.
I would look for a stuck blower relay.

Ac doesn/t blow cold air


There could be a leak in your a/c system. Does your a/c compressor engage when the a/c is turned on? To check, locate the compressor, its a big cylinder on the serpentine belt, you should see the wheel engage(spin) and disengage(stop) when the a/c is activated. If it doesn't move, then your compressor is bad. If it does move, then there is a leak in the system that will need to be repaired.

The AC compressor looks like this:

91 chevy 1500 pickup. When I turn the ac on the ac display flashes (never seen that before) and the compressor won't kick on.


you can buy a 4x4 actuator upgrade wiring kit from GM this will allow you to use the one big plug system (plastic actuator) the hardest part is routing one wire (I think brown) up to the floor shifter

AC stopped working


Try disconnecting the battery for a minute or so and reconnect it. Believe it or not this has worked for me numerous times. If this doesn't work then disconnect the switch on the accumulator. The accumulator is located in the low side (big) hose near the firewall on the passenger side of truck. Using a paperclip jump the two wires (harness side) together with engine running and a/c on. If compressor kicks on when jumped either it's low on freon or the switch is bad. Hope this is helpful.

Ac compressor won't kick on


Just had the same issue and posted. Just found the solution is the control module in the dash. Went to the junk yard since new is expensive on these units. Plugged new unit in, was able to charge a/c now blows cold as ice.
