2006 Boxster: Window won’t go all the way up

[DrLip]

2006 Boxster. Passenger window stops about.2 inches short of closing, makes grinding sound.

I’ve searched the web, seems that it’s either off the track, or a problem with the regulator assembly and/or motor.

Each time I roll it up, it stops in a slightly different place, accompanied by grinding.

Watching videos, it seems that if the window is still rising, although stopping before the top and making grinding sounds, this would indicate a problem with the regulator assembly catching or binding, and that the motor should be fine, since it is still pushing the window. I’m hoping to replace only the regulator, not the motor as well. Thoughts?

Any thoughts on how to get it closed temporarily, and cost of a fix?

Many thanks.

Hi,

You need to have the regulator replaced. The green plastic pulleys disintegrate over time, resulting in the grinding sound as the cables go haywire. Had to replace both doors' regulators, and learned that the aftermarket URO regulators rapidly fail due to bad design.
Here you should only use OEM Porsche part. I strongly recommend having an indie Porsche shop do the work as there is complicated work involved to remove/install airbag bombs, glass alignment, recalibrate electronics.

Hi Luislang, strange that anyone has said that about our 2006-2011 Boxster regulators. We've sold about 5,000 of 987 542 075 01-PRM and 987 542 076 01-PRM over the last seven years, and haven't had a single defect return in the last 365 days. (Going back further in our system would take some digging.)

Given these URO Premium regulators have a lifetime warranty, we'd certainly expect to hear about any failures.
