Why do your windshield wipers stay in the up position when turned off on your 2001 Olds Silhouette?

The windshield wipers on a 2001 Olds Silhouette may stay in the up position when turned off due to a malfunction in the wiper motor or the control switch. This could be caused by a faulty park switch that fails to signal the wipers to return to their resting position. Additionally, there may be an electrical issue or a problem with the wiper linkage that prevents them from functioning properly. Inspecting these components can help identify and resolve the issue.
