Could be the motor. The "park" portion is controlled by the motor.
You need to use a meter to test voltage to determine if the switch is feeding the motor.

1990 GMC Sierra 1500 pickup. Windshield wipers, Cruise Control

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.

Windshield wiper problem

Some of these trucks are covered under a recall. Call the dealer with your VIN number and they can tell you if its covered. IF its not covered, you will need to replace the WIPER CIRCUIT BOARD. or if you are real handy with a soldering iron, you can take the board out and ck for cracked solder joints. COMMON PROBLEM. ; )
