Puma power window failure
Summary of the thread
A 2021 Ford Puma diesel experienced a power window failure, with none of the windows functioning and an error in the window control system. The initial suspicion was a faulty power window switch. Another possibility suggested was a break in the main power or ground wire in the door jamb's wiring harness, which could affect all windows simultaneously. Ultimately, the issue was confirmed to be a defective power window switch, which was repaired at a workshop.

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.

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