Hi. I've a Venture 98' & lately I noticed that there are times when I can't close the passenger's side window from both sides. I can open it from both sides but the problem is closing it. Then there would be occassions that it's working ok. But it seems to be getting worse lately. Really would appreciate some help on this. Thanks.

Mine started doing that and it turned out the master switch located on the driver's door that controls both windows was on it's way out. I'd pull the switch up out of the arm rest and first check for a possible loose connection. These tend to be a problem with these vans as I have replaced both master switches in my 2 Ventures. When the master switch finally dies, you will not be able to raise or lower your passenger window by the switch on the passenger door. It might be a good time to check on prices for the switch. I ended up buying mine online through a GM dealer whose price was $25 lower than any price quoted to me locally,(and that included shipping.)
