slow rear windows

[NOMAD327]

I operated the rear windows on my 99 OBW the other day and noticed they move very slow, especially going up. They are normally not operated at all, and I assume they are just dirty. Anyone else have this problem and pursue it?

Yep, they all do that.....better to raise the rear windows with the engine running so the alternator is charging--they'll go up a little better that way. Or raise the windows while the doors are open. Obviously, the problem is that the door glass binds against the weatherstrip...........

 

On our '98 and '99, I've done 2 things that have helped: 1. On the interior surface of the glass (where the glass contacts the weatherstrip when the door is closed), you may see traces of weatherstrip rubber that have adheared to the glass because it's been in the "up" position for a long time. I used a NEW razor blade to gently scrape away this accumulation of rubber on the interior surface of the glass, then I thoroughly cleaned the glass with Windex. The inside glass surface that contacts the weatherstrip must be absolutely smooth and clean. 2. I then lubricated the window weatherstrips by soaking an old cloth with silicon spray (or use a little silicon di-electric grease) and wiping it on the weatherstrips. That allows the door glass to glide across the weatherstrip more smoothly--it reduces the drag so the glass goes up faster. If you use the silicon di-electric grease, it must be applied very sparingly--just enough to make the weatherstrip a little shinier--because if too much silicon is applied it'll get the glass all smeary-lookin' over time....

 

hope this helps........
