1997 Intrepid wiper motor won't stop even with key off: No codes

Question:

The windshield wiper motor will not stop until the fuse is taken off. I am scratching my head here because I thought replacing the wiper motor would fix it but to my surprise, it did not change anything. Suggestions?

ATS Adviser:

Symptom such as yours could be fixed by replacing the wiper motor because of a bad park switch located inside the wiper motor. However, a lot of this problem is also caused by a bad ground at the wiper motor housing and you can correct that by running a ground wire direct from the battery negative to the wiper motor housing. Assuming that won't fix it, replace the multi-function switch at your steering wheel.

ATS tips:

To verify the integrity of the wiper components, ATS can supply you the complete wiper motor wiring diagram so you can test the circuit.
