Wipers won't turn off automatically

[84 M1008]

Ok, I know this has been a problem with GM cars and trucks, but this is the first time I've ever had this happen. Any ideas would be greatly appreciated.

IIRC, make sure the single wire connector and the pin it goes to are clean and tightly connected. Otherwise, it’s likely an issue with the park switch, and the only remedy I know of is motor replacement.
