I've been trying to figure out why the previous owner of my car decided to run a wire from a toggle switch directly to the compressor to control the cycle.
As I was checking for obvious clues, I found that my a/c fuse was blown. I replaced it but the new one blew up as soon as I turned on the a/c. Could it be a bad a/c amplifier? How do I test it?
I have basic knowledge of how to use a mutlimeter tester & test light. Does anyone know where I should start if I were to trace the source of the short? Although my a/c cools just fine, I would really like to be able to restore the a/c electrical to its original design. I hate the fact that my compressor cannot cycle on & off automatically as well as the idle-up function.
Here's a copy of my wiring diagram. Please feel free to put notes on it & email as attachement to [email protected]
THANKS IN ADVANCE!
That diagram is not specific to your car. It doesn't even show an A/C amplifier. You'll probably want to find a better diagram, perhaps an alldata subscription.
Does the condenser fan run off of that same fuse? Could be a bad fan motor. If it's not that it's probably a wire shorted to ground somewhere. The usual check is to isolate parts of the system by unplugging them then test continuity to ground. Or put in a new fuse with some parts unplugged and see if the fuse holds.
Aux fan works fine. I had it unplugged when the 1st fuse blew. I will try the next component. Will the a/c work with the amplifier unplugged?
