Hi,
The AC in my 86 16V suddenly stopped working. The compressor will not engage. I opened the Klima relay and found a burn mark on one of the copper strips on the PCB which connects pins 5 and 7 through the relay to provide power to the compressor clutch. I soldered a wire to by pass the burned strip and the compressor engaged for about 10 seconds and cut out again. I opened the Klima relay again and found the same problem. I did this twice with the same results. Can a faulty clutch burn up the Klima relay? The compressor turns freely when I turn it by hand.
Thanks!
