2015 window regulator problem?

Hi there,

I have a 2015 i3 Rex. My driver's side window is flaky.

Comfort access upwards rarely works. The window doesn't often drop when I open the door, but does sometimes. The window is moving freely up and down, no issues.

For a while I was able to make it work by doing the regulator reset process (lower window, hold down, raise window and hole button up) but that's no longer working. I can't get it to reset anymore.

Does anyone know where I should start debugging this?

I have already purchased a replacement window regulator assembly, but they look like a pain to replace. It's also not clear to me if the regulator is the problem: what remembers the window positions?

Re: 2015 window regulator problem?

I had the same symptoms as yours. If your window going up and down fine, the regulator works fine. Once I change out the window switch, the relearn memory stays. I got a used switch from ebay for $40. Mine was a 2014 MY.

Good luck,
