UPDATE: WINDOW WON'T GO UP. REMOVED DOOR PANEL. FOUND BROKEN PIECE OF PLASTIC.
First, thanks to all who helped guide me to take the door panel off. No easy task. I misunderstood some advice.
Anyway, I could see why my window will not go up. It is a lousy white piece of plastic with a hole in it that split into 2 pieces. Is that the "sliding jaw" that cost $5.
Is fixing that as simple as getting the new piece of plastic (sliding jaw) and snapping it into place and then putting the metal rod back into the piece of plastic so the window can go up and down. The motor and connecting rod and working fine. It is just the plastic that broke.
What is that piece of white plastic called?
