What causes your windshield wipers on a 2001 Mercury Grand Marquis to shut off and remain in vertical position?

The most common cause for your windshield wipers on a 2001 Mercury Grand Marquis to shut off and remain in a vertical position is a blown fuse. The fuse for the windshield wipers is located in the fuse box, which is typically located under the hood of your car. Check the fuse box diagram to find the correct fuse for the windshield wipers, and replace it if necessary. If the fuse is not blown, there may be another issue with the wiring or the wiper motor itself. It is recommended to have your vehicle inspected by a qualified mechanic to diagnose the exact cause of the problem.
