QPower95

A few days ago I was sitting in my car with the door open waiting for it to warm up. The driver's side window suddenly rolled down about 1 inch by itself. I rolled the window back up and then pressed the switch expecting it to go down automatically, but it didn't. The auto down feature no longer works. This morning, now several days later. The window automatically started to go down by itself again, only about a half an inch this time.

Any idea what could be causing this? Relays, fuses, the switch itself? The window still works, it just doesn't have the auto function.

change the switch with a known good switch in your car. If the symptoms continue you've eliminated the switch as the problem and you must go deeper.
Do that and report your findings .
Good luck

Could this be the window lifters circuit breakers (see description under Fuse arrangement chart on same page in Owner's Manual) for the lifters reacting to some fault in your system?
