Does your door panel trim look like this?
How to repair:
Tools needed:
Replacement part
flat head screw driver or putty knife or what ever you have handy
stapler
First: Get a replacement. I had to get mine at a junkyard.
4 door cars remember: The ones off of the back do not fit on the front but the front ones fit each other and the back ones fit each other.
Second: Take off your door panel: First take off the screw covers. Then unscrew the the screws behind the covers. Now pop off the door panel with a putty knife or screwdriver or what ever you have handy.
Third: pop out the staples with a flat head.
Fourth: Put the new trim in place and staple it on.
Fifth: Put your door panel back on and the screws in and the covers back on.
Should look like this:
