So this sounds like a cluster pluck of the first magnitude---just one reason I hate some body shops. Mind you I once owned a body shop but NEVER resorted to quicky BS like described. It sounds as though the shop used polyurethane windshield adhesive, reasons completely unknown without me seeing the van in person.
I've done what follows on a brand new Navistar/International Harvester big rig with massive leak in a factory installed bunk side window. It's effective, not quite "proper" but works very, very well.
Using a painter's tape (blue masking) cover the body surrounding any leaking glass panel so the space between the body and glass edge is "open". (I'll post photos of this later today, when the sun comes up.) Do this as carefully as you want the finished project to appear, more time spent here yields a more pleasing completed appearance.
Next cover the glass itself trimming the tape with razor blade or other super sharp blade, the end result here being to leave a channel between the glass panel and body.
Using something like GE's Silicone II sealant/adhesive or similar high quality exterior grade 100% silicone sealant fill the created channel, slightly overfilling it so it spills over onto the masking tape. Any sort of putty knife can be used to tool the silicone into the channel and at the same time produce a flat surface that will be much less noticeable.
Almost immediately after sealant application remove the body-side tape by pulling it in line with the longest length of the glass panel; top and bottom you'll pull horizontally, sides vertically. This is to avoid any sealant strings landing on the body saving clean up time. Think of this action as pulling tape off towards the glass panel rather than towards the body---hope that makes sense?
Weather permitting you can tape all windows to be sealed in advance however apply sealant and remove tape just one panel at a time.
Van-essa I do have two questions though:
1. Does this van have the driver's side forward glass that's movable or pops out? Closest to the back of the driver's seat?
2. By pop out rear windows do you mean those in the rear hinged doors?
And finally I'll post a few photos of my masking tape "system" a bit later this day, as said when the sun comes up. Stay tuned!
