window problem? When it is wet here...

[rdane]

my power driver's side window is slow coming down. Is it just sticking because of the added friction from the water in the window guides or is it trying to tell me something?

thanks!

mine has done the same thing for years, and is now to the point where I have to assist it on the way down. I was told it could be a worn regulator or just needs adjusting.

Channel felt.

Those channel rubber/felts can be changed. Until then try some WD40 to dry them up, then some spray lube. Wax may also work.

the clectrics for the window isn't the best. maybe a voltage reading at the motor compared to battery voltage when running will give up some info. Sw are a common prob

My hand powered windows do the same thing.....very hard to turn them down, up is easy.
I usually spray WD-40 as a lube in the felt guides to assist in making them really easy but that lasts about 4-5 weeks and then they are sticky again.
The felt are in great condition......so I dont see how they could be the problem....can someone give more detailed explanation or a fix?

I find that WD-40 turns sticky..

fwiw, sometimes the glass and frame alignment in/out is causing some binding. After removing the panel and loosening the frame alignment multiple bolts I work the alignment to give the easiest glass load. It's sort of a comprise as your watching the frame move in & out.

Check the "squeegy" rubber seal. It gets hard over the years and is very easy to replace.

definately a good heads up.

the two outside rubber seals on each window is an easy fix with the frame out.. otherwise it's a pia and a near scratched paint.

The ouside "squeegy" is easy: Lower the window all the way, working from the INSIDE with a flat screwdriver, carefully lift the steel trim moulding which holds the rubber squeegy. The moulding is held to the door with clips fitting into small holes, it comes out fairly easy. Now you can slide the old rubber out, clean the trim moulding and slide the new rubber in with the help of some WD40. Put a little Vaseline onto the clips and pop them back into the door. It took about 30 minutes for both sides. The trick is to lower the window and work from the inside; no scratched paint. Cheers.

Silicone lube in the felt channels will speed things up. I found it lasted over a year before they started to slow again. WD40 lasted about a month.

My gues is a binding regulator - my left side broke altogether a few years back and needed to be replaced. The right side is hanging in there but needs help going down and goes up easy.

Porsche changed the design of the window regulators back in the mid 80's. The new design is the only one available now. It's not TOO difficult to replace, but you have to drill a new hole in the door braces and replace the runner on the bottom of the glass. A PIA actually.

The Haynes manual has a detailed procedure with a picture. As I said - I had to replace mine because it broke.

...now that I think about it, I saw an ad once for a doomahicky which fit on the old regulator to brace the stressed joint. It wasn't cheap, but a lot cheaper than a whole new regulator and guide rail. I *think* PP had the part, but maybe Wayne does too.
