Is the a/c relay my problem? i just re-charged my a/c system with 134a. however, yesterday my fan blower and compressor quit working. diagnosis: fuses not blown, new fan blower,new fan blower switch, a/c system still has full charge. it started working and then stopped again three times yesterday. When it stops working, my radiator electric fan still comes on when i select a/c on my control switch which lets me know my selector switch is working properly. AND, my GM service manual refers me to section 8a (a/c wiring diagram) but the index of the manual does not list section 8a and the manual does not contain section 8a

 

UPDATE: Replaced the relay and everything started working!! HOWEVER, I just drove the car and now it is doing the same old thing. Any ideas what to do next

 

might be the relay harness?
