Is it the window regulator?

[MirrorMuscles]

987 - 2008
The cold icy weather took its toll on my driver's side window when it was iced up. The window went through its cycle of trying to drop when I first opened the door without success. I got in, shut door, drove to work. Opened window at barrier and it went down. Barrier went up after showing my card.....window did not. Tried pulling it up, got a colleague to hold button in up position whilst I pulled - nothing. I left car with window half open. I then went back to car 2 hours later and wondered whether it would go back up if engine was running. I push button up, it moved an inch, then push button down, it moved 2 inches, pushed button up, it moved 3 inches, pushed button down etc etc and it finally went up. Unfortunately that is the last time the window worked. It won't go up or down. The drop doesn't happen when I open the door. However when the door is opened and I manually push window down for the drop, it does automatically go up when I close the door. When I do push the button to operate the windows, although the window won't go down, it just makes the same noise as it would if working - no crunching just a quick whirr.
I have watched the regulator replacement videos, still can't work out how that thing raises and lowers the window - In any event, what thinks the panel, is it the regulator?
Thank you so much in advance for your reply

Sounds to me as though the runners are wet and sticking, the cure may be to strip it but the membranes between door card and aperture are damn expensive!

It's also possible that the cables are strained or sticking, they are in a figure eight layout so that both ends go up and down together but any mismatch can put the window on an angle and jam!

I had the same issue on my 2009 987.1 Boxster. It actually became a bit of a concern each frosty morning when I came to open the drivers door.

It came to the point that I was leaving the car with the window ajar, just so the window didn't have to drop when the door opened. I have been using a

top half cover most nights, (this is waterproof and breathable), to help eliminate the problem. At its worst the door would not close properly, so one day I drove to work with it on the latch if that makes any sense? In this mode the window would not operate. Once the glass had warmed up, I stopped, opened the door and the window mechanism brought it fully up, and the door closed properly. My concern was as has happened to you that the mechanism would break and I would be met with a costly repair bill. Surely Porsche must have tested this in the design stages? Anyone else had this issue or ways to avoid it?

Thanks.

It sounds very much like the regulator. The drivers window in my 987S went at Christmas.

So, after a fashion it would go up but not down. It didn't lower to open the door either. The button made the clicking sound and the motor sounded as it was working but no window movement and it also sounded as though there was something loose in the workings.

I attempted to remove my door card and investigate further but gave up as it was so difficult due to it never being removed before.

Revolution Porsche at Brighouse confirmed the diagnosis and charged 285 for original part and fitting which after i calmed down was quite happy about.

I caused the issue by slamming the door shut whilst winding the window down so only had myself to blame,

cheers if this helps
