I believe that the A/C Compressor on my 94 XLT has gone out. I tried a few things to diagnose it that I found on these forums and I'm still not sure. The compressor will not turn on. I tried swapping the A/C-WOT relay and it did not come on. Next I tried jumping the low- pressure switch on the accumulator/ drier (hopefully I checked the correct spot on this, If someone could post a pic it would be great), that didn't affect anything either. Lastly; I jumped the compressor with 12v from the battery and it engages and spins. However when it kicks on it squeals very badly and a pink dust comes out of the compressor. Also after a few seconds the compressor will seize up and stop spinning. I am pretty sure the compressor needs replaced and will likely be replaced no matter if its the actual cause or not. I am mostly wondering if there is a reason why jumping the compressor will turn it on while checking the other items wouldn't (some safety in the compressor maybe). Thanks for the help.
