95 Bonnie, went to check my air and get it ready for the weekend, and i notice my compressor hasnt been kickn in. Usually if its runnin and i open the hood you can see when the compressor engaeges and disengages. so i figured ill unplug the pigtail and test for voltage. didnt receive any voltage with car runnin or just n the run posistion. so does anyone no which relays are which under thge hood near firewall ? really gonna need it with this 90 degree fathers day their predicting, and i have leather !!

you cant take that as gospel, you need to check the pressure, it probably had a slow leak. my car has had a leak ive been trying to track down for a while. you can fill it in spring, use it all summer and the first time you go to use it in the spring again it will be gone.

I moved your thread into the Bonneville Mechanical & Maintenance section. More of us Bonneville fans should see it now.
What are you getting out of the vents? If it'* blowing hot air, that can mean that your A/C system is overcharged.

If the 95 is similar in design to the 93, I just finished replacing my compressor and converting over to R134a. My 93 has a pressure switch located on the accumulator. Unplug the switch and jump it with a paper clip. On the 93 this kicks in the 2nd cooling fan and the compressor (if no fuses are blown elsewhere). If the compressor kicks in while jumped, it'* low on refrigerant and will require a charge. If it doesn't kick in, start checking all the fuses and connectors. What I discovered after replacing my compressor and it not turning on when jumping the switch was that the 93 has an auxillary fuse panel under the glove box. I found a fuse in there that was a 15 amp fuse and was marked 'misc eng. controls' and it was blown. It controlled the a/c compressor, the cruise control and I thibk the OBD1 port. Check your owners manual under the fuse section and see if you have the 2nd fuse panel. Hope this helps ya.
