1994 Caprice AC blows fuses

[jkayes]

Have replaced AC Comp relay and it's still blowing fuses. Any ideas?

Is it blowing the HVAC fuse or the blower fuse?

Try unpluging all of the switches and the compressor and the relay. Install the fuse and if it doesnt blow, plug the switches and the comp in one by one till the fuse blows and that is the part of the curcuit that is causing the problems.

I had a caprice blowing the HVAC fuse from a bad high pressure switch in the back side of the compressor. Might be a good place to start.
