Puma power window failure

Sounds like a faulty window regulator. Have you checked the wiring harness in the door jamb for any damage?

Thanks, I haven't checked the wiring harness in the door jamb yet. Would that really stop all the windows working at the same time? I thought each window had its own wiring.

Yes, a break in the main power or ground wire in the harness can knock out all windows. Uncommon, but it happens. Window regulator is the more common issue. Best to get it checked at a workshop.

Thanks for the insights. I had it checked at a workshop, and it was a defective power window switch, like I thought. The repair was about 200€ including parts and labor. I appreciate the help with diagnosing it.
