My a/c compressor and condensor fan will not turn on. I'm quite sure its because I have low freon, I need to get it recharged with R12 every 3 years. But also my radiator fan does not turn on either. According to the fsm, if the AC pressure is too high or low (in my case) the dual pressure switch sends a kill signal to the AC switch, the AC switch in turn sends a kill signal to the compressor, condensor fan and radiator fan. Does this seem right? I thought the radiator fan was independant of the A/C system. I checked the radiator fan and radiator relay switch and both were good.

Any comments?

 

this might be a dumb question, but im only asking cause it seems that little stuff is often over looked, you said you checked the fan motor and relay, theres a fuse as well. did you used a test light to see if the motor was even getting power, or did you hook it directly to your battery to test?

also, my ac system is shot (im actually working on it now) if im not mistaken, my ac fan came on even though my system wouldnt hold freon.
