Sticking Windows

Probably the biggest design fault in the Vehicross are its windows. Nearly every owner has had to deal with this problem. The most common symptom is windows that roll down fast, but up slowly. They may begin to come loose, and you will find excess play in the glass. Eventually, the glass will come out of the frame, and bind up entirely.

When you look inside the door, you will often find one or more of the plastic clips connecting the glass to the regulator are broken or detached. These clips are not available from the dealer -- they only sell the entire window glass as a unit.

Window Alignment Theories
Some owners have postulated that poor alignment of the windows/regulators is the underlying cause of this problem, leading to extra stress on the clips that eventually destroys them. It has been noted that unlike many other vehicles, the Vehicross doesn't have any provision for adjusting the alignment of the window regulators. This is a problem when combined with reports that the action of the regulators as they are mounted is not parallel with the motion of the window glass.

Temporary Fixes

 * Lubrication - Many owners recommend using a silicone-based spray lubricant regularly. Using the red 'straw' attachment, liberally lubricate the rubber channels that the window sits in. About once a season seems to be sufficient.
 * Different Clips - Some owners have tried clips from other GM vehicles, which appear to work.
 * Adjustments - Some owners have had luck with installing washers to adjust the angle of attack on the windows.

Permanent Fixes

 * The most common fix is the Street Boutique window fix. This replaces the fragile plastic window clips with metal. The piece is also adjustable, so that you can ensure that the window rides in the correct path.
 * The Street Boutique Customs page went down in early 2021. You can view an archived version here.

I experienced problems with both windows upon buying mine used. However, it turns out I had multiple problems.

On the driver's side, I had the clip problem. I was able to replace them with auto part store GM clips (similar to Dorman 1330824). I selected a high-flexibility epoxy adhesive. This seems to have held.

The larger problem is a plastic carriage that is supposed to clamp around the metal rail. In normal use, this keeps the window even while it is moving. However, the white plastic has become fragile and the section that wraps the rail has broken. So, the whole window falls off the rail, and becomes crooked and it all goes bad from there.

I was able to replace this carrier on the driver side with one from a wrecked VX, but this is a messy and difficult pull. This has been more or less effective, though.

I corrected the broken clip problem on the passenger side with the Street Boutique clips. I selected a high-flexibility epoxy adhesive, again. Together, this all briefly worked, but over the decade, they've begun to rust away into nothing, and the track carriage has broken and I haven't replaced those parts.
