Cabriolet rear side window.

Recommended Posts

I've had a Smart-Top module in my Cabriolet for a couple of years, however lately when closing the top the right rear window will on occasion go only 2/3s the way up. I am able to manually close it with the switch on the drivers door, but that is a pain. I periodically clean the track with silicon spray, but the problem persists. I initially thought that maybe the Smart Top module had gone stupid on me, but the local Porsche dealer thinks it's the regulator. The top gets lots of up and down usage here in Arizona and I don't want the window to cease operating entirely, but the dealers estimate of $1K to fix it was a bit unsettling. Have any of you had this problem and if so how did you deal with it?? Does anyone know of a DIY to replace the regulator if that is really the problem?

Thx, Lyn

If everything else works fine (soft top open & close, hydraulic rams/pump system, cover lid open/close, etc), I think the culprit is probably the window regulator/motor (Part#  997 543 016 02). I guess that it will take a lot of work to reach that part for replacement.
