A C issues

mikerike · 07-19-2006, 06:06 PM

Folks help me out!
AC not working. Fuses good: relay not sure.
Clutch will pull in with direct 12 volts from battery.
System charged a week ago and charge gauge still reads the same, so i doubt there is leak in system.
Any Help would be appreciated.

Thanks,
Diagram and points of checking would be helpful.

bradrhale · 07-20-2006, 07:01 AM

need more information, will the clutch pull in when you turn it on?? is the fan on, what kind of vehicle??

mikerike · 07-20-2006, 04:46 PM

Vehicle is a 1995 GMC 4X4 pickup extended cab
5.7 engine, auto transmission
Clutch does not pull in when started but clutch does work if I supply 12 volts directly.

all i can say is that 've dealt with more GM's than anything else, and the majority of em had a non-working AC system

more than likely it is going to be in the switch, relay, or a fuse. check those and sure you ll find the problem

i would trace your wires, your relays and the like, sounds like you have a short or a disconnected wire.

Relay good
How do you check pressure switch

Thanks,

to check the pressure switch, take the connector loose and using a paper clip or some other kind of jumper, complete the circuit. if it does and didnt before, itll be bad. if there is no change than it should still be working as long as you still have good pressure on your guages.
