I know this is an old topic but I have not yet found the answer to my problem here in the forum. My AC blows hot, but the AC light does NOT blink. It is ON. Changing to heat or defrost causes air door to move, as seen looking into small opening over driveline hump. Also defrost causes idle speed to increase. However, in normal mode, ac fan does not kick in, compressor does not activate.
Last time in the shop, the replaced refrigerant in system... but mechanic said something like he wiggled a relay and the system started working... However, the problem is NOT the relays, as I have bypassed them to test and clutch engages, fan runs, but still no cool.
How do I find an error code? Where is the low pressure switch?
Thanks!
