Dear DML, Thank you for your kind suggestions on how to solve my toll booth window woes. What I ended up doing though, was calling Steven Wynne at DMC Houston. He said that the problem was that the window was too far to one direction or the other, and that was causing the carrier to pop off the guide. Even Gus' suggestion of leaving the interior trim off helped a bit. After receiving help from DMC Houston, I went out to the car and ran the window up and down, with interior trim off, while watching what happened to the carrier and guides. While running the window up, I noticed that the window was too far forward in the carrier, causing the carrier to be pushed backward, pulling the front end off the guide. Went to an auto glass place and had them take the window out of the carrier and got some auto glass urethane adhesive. Back at home, put the glue on the carrier, and put the carrier back in the door. Slid the window back into the carrier, ran the carrier up to the top, and used a screwdriver to push the carrier up as far as it would go. Waited for glue to dry, ran window up and down, and success! The carrier was no longer pulled off the front guide. Hope this might be of help to someone who has the same problem I did.
