A/C Issues... Help??

SableSal · Sep 18, 2009

Well, I have a 95GT and the A/C isn't working. Now, I did some trouble shooting and did find that the compressor is not getting any voltage at the clutch coil. Now, what are the possibilities? I did check all fuses and the control unit. All checked good. I know there's a low pressure switch that if bypassed should trigger it on. I've bypassed it, and it's still not getting power. What else could be the problem?

Thanks in advance!

The system really only has one control, and that is the cycle switch located on top of the dryer accumulator. The cycle switch will turn the compressor off if the pressure is too low, or too high. If you unplug the cycle switch and bridge the terminal on the pigtail with a paper clip, the compressor should turn on. If it doesn't turn on, it is most likely the compressor relay that has failed.

I did replace the relay and still nothing. I'm assuming it could be the switch at the receiver drier. Now, there are four wires at that switch. Which do I connect with a jumper wire? I'm thinking on just replacing both switches.

Let me know!

Should be only 2 wires.

That's on the low pressure / Clutch Cycling switch... Hold on. I need to take another look. I think there may be another switch around there. We'll see.

At the firewall on top of the condenser. Only two wires and cannot be confused with any thing else in that area.
