The open/close works,
but is sometimes hesitant or requires a hand push/pull to get it moving. A couple times I could not make it power closed. It seems the rails are lubed and things are aligned right.
Are there any hints on giving it more oomph?
Stiffening up the slip clutch? if it has one...
Better electrical current and contacts?
Lube with super lube?

hammer?

use the air conditioner?...

 

I had the same problem earlier this spring. Probably because it was unused all winter. Easy fix, spray some silicone lub spray on the rails and problem solved! IMHO works 10 times better than your standard greese. Just make sure you clean any debris or dirt from the rails first. Works great on the doors too, you can pick it up at your local hardware store. Good luck

 

hmmm, i think i need to do that w/ my windows

 

Had the same situation a year or so ago. Found the sunroof switch's internal contacts sort of 'burnt'. Took the switch apart and cleaned the contacts with fine file. Has worked great every since.

 

Mine was the same way when I first got my car. I cleaned and greased the rails, work great now.

 

i dont mean to be rude or anything but wasnt this car on ebay?

 

Is your camera's color balance off, or is that really a purple 7?

 

The Ebay connection is right...
$6000 dollar paint job, and been putting a car back under it.
It is colorshift paint, I think it is Dupont's colorshift, but I do not have records.
Green at noon, purple at twilight, black at night?
