Kadjar power window failure
Summary of the thread
A 2016 Renault Kadjar diesel experienced a power window failure, with an error stored, leading to suspicion of a faulty power window switch. Possible causes included issues with the window mechanism, loose connections, or damage to the window control unit. It was suggested to inspect the door panel for water damage, corrosion, or wiring issues, and to consider a workshop visit due to the stored error. Ultimately, the problem was confirmed to be a defective power window switch, which was repaired at a workshop.

How do I inspect the door panel and window control unit? What should I look for?

Check the door panel for water damage or corrosion. Examine the wiring harness to the window motor and control unit for frayed or broken wires. Given the Kadjar's mileage, the window motor might be failing and drawing too much current, causing the error. Because there's an error stored, I'd recommend a workshop visit. Replacing parts randomly can get expensive.

Thanks, I'll consider that. I got it repaired at a workshop. The original guess was right; the power window switch was defective. The total repair cost was 200€.

I remember a friend's Mégane having similar issues, and the window mechanism was the problem. Have you checked the door panel for loose connections or damage to the window control unit? Investigate all potential causes before assuming.
