    I believe they are where the weatherstripping is connected to the plastic...I did mine about two years ago....once you get the panel off you will see them....what a pain to take out .... I replaced the staples with thin copper wire that I issues since

    So is the real issue the weatherstripping attached to the plastic door panel? The stress point is the 90 degree area where the crack starts in the picture. Same reason they put a grind relief on a crankshaft journal or saw cuts into concrete.

    When they installed the weatherstripping the panels were more than likely torqued, so this put constant tension on them. After a few years cooking in the sun, and the plastic becoming more brittle, they give way.

    I fixed mine following the directions using the machine screws. I replaced almost every staple too.

    Here's my before/after:

    Once you take your door panel off, you will notice the staples holding the weatherstripping on. Those are the staples that need to be taken out in order to "stress-relieve" the plastic. I drilled small holes once I took out the staples and put in small 8-32 screws with washers and backing nuts through the weatherstripping and through the plastic panel. Be sure to take the staples out before drilling your holes and give it a few minutes to relax. Drill the holes near or even through the holes where the staples were once it relaxes. I used permatex medium strength threadlocker blue on final assembly. I cut the ends of the screws off with electricians wire strippers and then applied the threadlocker to keep the nuts from loosening up. I did mine before the cracks started as a pre emptive effort. That was about 4 years ago, and they are still holding!
