Why don't the windshield wipers in a 1985 Mercury Grand Marquis turn off?

Windshield wiper motors have an internal switch that allows a wiper motor to stay running long enough to keep the wipers moving until they reach the "park" position. Once the wiper gets to the park position, the wiper motor is shut off. The internal switch often fails and either the motor will shut off immediately, wherever it is or it will keep running. It sure seems that you need a new wiper motor.

Why do 2001 mercury grand marquis wind shield wipers stay up when off?
I had the same problem with my 92 Grand Marquis. Seems that the windshield wiper motor was running in the opposite direction for one reason or another. You may need to replace the motor or have someone look at it. Fortunately for me, my mechanic drilled a hold on the motor and flipped around, now my windshield wipers stay down when not being used, however they stay up when in use... weird.
