take it to a local car dealer they will be able to help you out. Do you still have a warranty? If so then do not touch anything as you may void the warranty. Being that it is from 1993, I would go to a local cheap dealer to get it done for 50 bucks. Just google " car repairs" Good Luck!
Messing with electrical repairs is a pain because it is hard to find out what caused the problem. I suggest taking it to a repair shop (not the dealer because they are always too expensive and being a 93 your warranty is long gone)
