I think I need to do it too.
Thanks for the tip, and a huge thank you for searching!!! Welcome to the 'Fest!Went thru all of the glueing, stretching of vinyl and clamping but door would not stay on anyway. The cardboard looking stuff inside the door had softened to where the clips just pulled out in a few places. We solved it by drilling a small hole thru the door panel and anchoring a 2" screw in a drywall anchor. Not ideal but doesn't look too bad and the doorpanel stays tight. to reglue the vinyl I used a blowdryer to stretch the material and then glued it in place with silicone. Looks WAY better than before.
Where can i buy that top clip????? i broke mine taking it offThere is a clip panel at the TOP of the door as well. This usually separates, particularly when removing the door panel. Many assume (as I did, initially) that this was part of the door, as it separates so cleanly that you don't realize it was originally glued to the door panel.
Remove the interior window weatherstrip (pull straight up) and then carefully pull this piece out.
Then glue it in place to the door panel (it will fit like a glove in the right location). RTV silicone, like you used, is the best. I used a latex adhesive caulk (which I had laying around) and that worked OK, too.
IN short, the door is held in on all four sides: Front and rear with the clip strips (as you show), at the top with a clip rail, and at the bottom with the storage compartments.
Make sure all FOUR items are properly glued in place. Once reinstalled, re-insert the window interior rubber gasket, and if you align it carefully, it will fill in the space between the door panel and the window just like the day it left the factory.
