windshield wiper problem...please help

[1990 HOSS]

ok...i got a 90 gt and the wipers have completely quit on me. I bought a wiper switch(Turn switch lever) and the wipers worked for a day or two. I dont know if there is a short somewhere or what. One of the receptacles on one of the 3 plugs that plug into switch looked as if it has overheated and partially melted. I'm assuming that's probaly going to be my problem. I checked for fire going to the wiper motor and found fire on one of the 2 plugs on motor. Test light lit up with keyswitch on and off. Should both plugs have fire? Any ideas or suggestions would greatly be appreciated. By the way, I used a paperclip in place of the circuit breaker...still...no wipers...please help

A word of caution about multifunction switches is in order here. The multifunction switch (high/low beam, wiper, turn signals) are different for different years. 87-98 will work in any 87-89 car. The 90-93 switches only work in 90-93 cars. You can't put an early model switch in a late model car, nor can you put a late model switch in an early car.

Have you tested the motor? If you have verified 12V from the MFS (multi function switch) to the motor and still do not have a functioning system, I would assume that your motor is shot.
