any ideas? It was working gine yesterday and today it wouldn't work. no stange noises or anything .... tia

well, assuming it attempts to as far as the eatc and the air control doors goes (it sends air to the panel vents and fan is running, with no air going across heater core), their is only a couple things that will keep the compressor from running... low pressure in system (the low press cut out switch opening to protect the compressor), excess pressure (same switch used to protect compressor and system from pressures being too high), or clutch not engaging.

need to know if the refridgerant pressures are right before jumping to conclusions...

well I finally got it in the shop they replaced a switch that didn't work the mechanic said it was something electrical either the control unit or some black box by the radiator. either way the a/c has worked once since then but doesn't currently.

my 00 V6 is blowing hot air on one side. Sometimes it blows hot on the other side, while attempting to blow cool air on the opposite side. The shop is telling me it is the heater/water control valve.
