Master Power Window Error

Hello there. I had similar issues with my Renault Master too. A window regulator, sometimes called a window motor, is an electrical device in your car door. Its function is to lower and raise the car window when you press the window control switch. Was the error specifically about the window regulator needing initialization?

Yes, the error message refers to the window regulator initialization being unsuccessful. What did you do to fix your issue? Was it the same error?

Yes, that's exactly the same problem I had. In the end, I had to take it to a workshop. The car electronics sometimes need a reset after the battery is disconnected, which requires special tools. They were able to re-initialize the window regulator and clear the error. It wasn't cheap, but it solved the problem.

Thanks for the info! I had a feeling I would need to visit a workshop. Just got back from the shop - the bill was 290€, but the windows are working again!
