For the record, I know for sure the compressor did not kick on when I
jumped the switch. And the piece of wire that I jumped it with ( 16
guage stranded) got hot. It's like as if I shorted out the battery,
thats how big the spark is. This car did have some work done on it
recently ( again, this is not my car, it belongs to my brother-in-law).
So it's possible the wiring got screwed up.
But even with the big spark, I would expect a fuse to blow. This is why
I'm a bit stumped.
