I just bought a 1988 Cadillac Brougham now i would like to fix a few electric things that don't work. Those are the interior lights the automatic door locks and the radio makes strange cracking noises. I don't know if that is all connected or if these are all different issues. Could it be just one fuse? Where are the fuses for these 3 things located? Are that common issues? Thanks in advance.

There were two cable not pluged into the back of the radio. The annoying noise is gone I can play cassettes but i still dont get any radio stations. I found a blown fuse for interior lights an cigarette lighter were im gona buy a new one. Seems like everything is fixed but...
while I was looking for the fusebox my dad said we should wash the engine so he put some stuff on there and rinsed it off with a garden hose.
Today the car didn't start! grr...
Did something get wet? What could that be?
Please asked if you need any further information.
