First if you have not done so alreadyis to check the fuses, relays (the a/c relay is the same one for the horn side by side, if the horn works switch the relays, if the horn still works the relay is good) if they are all good then turn on your a/c and check to see if the a/c compresure comes on ie clutch ingaged. If not then it can be one of two things either you are low on R134 or the compresure clutch has gone bad. oh ya there is also a high pressure switch on the passenger side of the car in front of the air cleaner box, that is on of the other possibility. I had a mobile machanice come by and run a test and he unpluged the high pressure switch and jumped two of the wires and coame up with answer that my a/c clutch was the problem. Schucks had a remanufactured unit for $198.99 plus shipping and core. I live in Washington state. Hope this helps. Good luck.

Is there a fuse or relay for the heater in my 2002 ford expedition


No hot air is due to low coolant, or even poor coolant flow. The engine heats up the coolant, and it passed through your heater core, and the heater blower motor pushes air through the heater core to warm up the air. If your "fan"is working, but the air is cold, make sure your coolant level is good.

I have a 20000 nessan quest and the airconditioning was working great but all of a sudden the air got warm so I put in 3 cans of freon, then changed the selector but still I get warm air when it was...


3 cans should overcharge & possibly ruin the system

Leave A/C work to the trained mechanics

You need at least a week long class, to even learn the
theory of Air Conditioning for any system & cars are not
the same as commercial work. I think they are harder
to diagnose & work on.

Aircondition not working....just blowing warm air.....fan is working


Either you are out of coolent or the compressor is not working.

First check the fuses, then lift the hood and have a friend turn the air on. The compressor should cycle, if not take it to a mechanic. If it does cycle you are low on freon, take it to a mechanic for a system charge. Make sure they check for leaks first.
