One day it works, the next it doesn't

95Convert · 06-03-2001, 10:35 AM

Okay here's the deal. The air conditioner on my '95 has a full charge, and no leaks. It worked fine one day and the next it didn't. I noticed that when I turn the switch to the A/C position, the clutch did not engage on the compressor. I got out my multi-meter, and sure enough, no power to the compressor. Is there a fuse or relay that would be the cause? I'm new to the SN95 cars. Any help would be appreciated

not to state the obvious, but did you check your fuse panel yet to see if you blew the fuse?

I'd check the pressure switch (its mounted on the accumulator on the firewall right side) I believe its normally open, so if you unplug it, the compressor should kick on. (Its been awhile, so I'm not 100% sure on that) Thats if the switch is bad, of course.

Okay, according to all my sources, there is not a "fuse" for the a/c, just the heater/ac blower motor in the car. I'll have to check the pressure switch.
