Driver Window Grinds When Fully Rolled Up

Driver side electric window will roll down and up fine with no issues but once it's rolled all the way up to the top it will start grinding and act like it want to keep rolling up. Are the teeth on the actual motor shot? What all do I need to replace for the guru's that's had this issue?

Mine too. Doesn't effect function, just have to stop when you get it closed or it fusses at you.

Mine's been doing that for 2 years. $43 and 20 minutes of your time will fix it. I buy my parts here. 10 year warranty and no questions asked for warranty replacements.

Most likely, your balls are broken. No, not those, the ones in the window regulator. There are three plastic balls inside the regulator, located just underneath the cover that the gear comes through. They are intended as a shear joint. The idea is that the balls will break instead of breaking an arm or a hand if the window gets rolled up on someone. With age, these balls will get weak, and will just fail out of the blue one day. It takes away the safety feature, but you can fix this issue as simply as cleaning the crumbled remains of the balls out, and dropping three 1/4" hex nuts back in in their place, or three balls from a ball bearing if you have any the correct size laying around.

4-wheeling: because football, basketball, baseball, and golf only require one ball!
