My first post to this forum, hoping someone can help. I had my AC charged in my 1980 Vette just before needing it this past spring. I used it long enough to be sure t was cooling properly and basically parked the car. Recently I went to take it for a spin and turned on the AC. It appeared to be cooling properly for the first couple of miles and then it just stopped. I mean now I don't even have a working fan switch even with the AC in the off positon. When attempting to activate the AC using the switch I can see there is no power to activate the AC magnetic clutch My thought is checking for a blown buss fuse, or maybe multiple fuses? Any one out there ever experience this or have any ideas? Any help will be totally appreciated. Longrun.

I'm going to move your thread into the C3 Tech forum for greater exposure.

I'm not sure if the fan and the compressoer clutch are on the same fuse or not. Your owners manual should tell you which fuses to check.

Welcome to CAC!!!!
check the fuse in the fuse box 1st,for the heater and a/c...
there is a separate fuse for the fan.I would start there....
good luck
