My wiper blades won't go down when I shut them off. They stop straight up on the window. What should I try?

Check the wiper arms at the windshield pivots for binding. If they move freely, replace the pulse control circuit board in the wiper motor, which contains the park switch logic.
A 1998 Chevrolet Camaro owner reported that the wiper blades stop straight up on the windshield instead of parking down when switched off. One reply suggested checking the wiper arms at their pivots for binding and inspecting the wiper motor for wear. The expert said the park switch logic is inside the wiper motor and recommended replacing the pulse control circuit board, noting it is inexpensive.
