Where is the GEM located for windshield wipers and dome light on a 1997 F-150 extended cab?

The Generic Electronic Module (GEM) in a 1997 Ford F-150 extended cab is typically located underneath the dashboard, on the driver's side. It's often near the steering column, but its exact position can vary slightly depending on specific trim levels and options. You might need to remove some trim panels to access it.

Since it controls many functions, including windshield wipers and the dome light, it's a central component. However, before you start dismantling your dash, consult a repair manual specific to your 1997 F-150. These manuals provide diagrams and detailed instructions to avoid damage. A wiring diagram will help you trace the circuits involved to be certain the GEM is the source of the problem. It's possible the issue lies elsewhere in the wiring harness or with a switch.
