I couldn't get them to load here so...... anyway the glass in the left door acts fine till its about 3/4 of the way down then tilts forward there are multiple pictures in the repair folder ....water seems to have leaked in over the years and there is some rust on the inside of the door hollow...mostly near the front at the hinges. Is this going to be a problem?
Thanks

I guess I'd check out the front and back vertical channels first to make sure they're anchored properly and not spreading when the window gets near the bottom. Rust on the door shell shouldn't affect the regulator operation. Check the horizontal channel on the window as well for binding. The regulators are all interchangeable for these doors.

The tabs on the glass channel on the bottom of the window are either bent or broke. If they are 1/8" off the glass will rotate in the verticle channels.
