Door glass popping out at speed

Got new a/c flowing, pressurized interior now causing tops of door glass to tilt out of weatherstrip. I am missing roof rail channel glass clips causing it. Any pics or advice on exactly were to mount new clips??

Pressure relief is normally provided via the black triangular vents in the "B" pillar below each door latch. These let pressurized interior air into the rear quarters with that air then escaping out through openings in the trunk lid back edge seam, and out drain holes in the trunk floor drop off lowest point. Check that the relief vents are working and that the air exits in the truck area are not blocked or clogged.

I’ve dealt with this problem. My fix was to read up on the correct way to mount the window panes and regulators into the door or body. Mine did the same thing yours are doing, and if you were outside of the car with windows up and pushed inward on the top of the window, mine would actually move inward and seat in the correct groove of the weather strip seal, indicating to me they weren’t installed correctly.
A shop manual describes the process for installing and adjusting the windows. It’s easy and works.

Good luck

A correction about what I wrote about pressure relief above. Air entering the passenger cabin via the cowl (heater or AC fresh, not recirculate mode) creates a slight increase in cabin pressure. The air coming in displaces air already in the cabin. The cabin air is forced into the rear quarter panel areas and the trunk as the cabin is deliberately not sealed off to prevent that. The air forced into the quarter panel trunk space is forced out the "B" pillar triangular vents located below the door latches, then out around the gaps between the door and body. If those vents are faulty or the cabin was sealed off from the quarters and trunk the incoming air has to force the existing air out somewhere else such as around the side windows.

Do the chrome trims gave these clips?



These are to keep the window glass in when fully wound up.

Yes, those are the clips! Man, I totally forgot, I bought ford repair manual set last year!! I forget my own name sometimes!!
