Hello friends. I'll start this with my token gesture of appreciation for all the great advice I always receive on this board... I recently was able to fix my air conditioning woes (the electrical connection was actually shot, suprisingly that was it!). Pretty much around the time I was able to get my AC going, my windows stopped working, all of them. Going off the wiring diagram in my Haynes manual, the window lift relays are on the left side of the engine bay, under a black plastic cover. I tested both the relays and they seem to work fine. However, when I ran my multimeter on the boards the relays plug into, the one further out appears to have a ground (the multimeter pegs out all the way to the left). I tried tracing the wiring bundle into the car to see where everything connects to to see if I could physically find a ground. After giving that up, I noticed my AC stopped working again, and the blower wouldn't even come on. I checked the fuse panel and saw that the fuse appeared to be burnt, but in tact. I still changed it out and with the new fuse, the system came back on. After I turned the car off, then back on for another reason, and checked the system again, it had burned the new fuse. I tried one more fuse and everything seemed to work (I thought the new fuse I used (actually older, possibly used and abused) may have just been bad. On my drive, I noticed a different smell coming through the vents. I shut the car down to get some fuel and when I started it back up, the AC and blower again weren't working. I looked at the fuse and she was toasted pretty bad, again.. and this one was brand new.

I WAS going to disconnect the compressor and see if maybe somehow that was spiking the system and burning the fuse out? The clip that holds the fuse though looked blackened somewhat so I wanted to get some advice from the masters here!

My two issues are trying to find the right relay for the windows, and if I was right with which one it is, trying to find the ground, or possibly just replacing all the wiring. Second, trying to figure out what in the circuit that provides power to the blower, compressor and other accesories is causing the fuses to blow/burn out.

Thank you all in advance for your advice.

Best,
Paul

Remove the offending fuse. Using a voltmeter, identify the 12V and the 0V sides of the fuseholder. Now connect an ohmmeter from the 0V side to ground and see if there is a short (no resistance). Leaving the ohmmeter connected, start disconnecting the equipment on this circuit until the short goes away; you have found the offending circuit. Now move into that circuit to isolate the offending component.
