How do you replace a power window motor in a 2000 gmc jimmy?

Answer 1

Start by removing the two Phillips screws in the door handle. Then remove the three holding the plastic trim strip at the back of the door next to the window. Now pull off the door panel. Grab the bottom of the panel and work your fingers behind it and just pull. It is held on by 5 or 6 plastic snaps. They might break but you can buy new ones at any parts store for like 2 or 3 bucks. To have easy access to the motor, unbolt the door handle bracket and remove all the plastic and foam insulation on the door. The bracket is the thing in the middle of the door sticking out with two 10mm bolts holding it down. There are now five rivets holding the motor in. It is actually attached to the entire window lifting mechanism and has to come out as one piece. I punched out the centers of the rivets and drilled them out with like a 1/4" drill bit. When there are two left you may want to brace the window up or have someone hold on to it because it will slide down on you. There is an electrical connector hooked to the assembly which you can unclip with your fingers. It is in one of the smaller holes toward the front of the door. Now you see at the big hole in the back of the door an arm that pushes the window up and down. With the window slid up and the rivets out, haggle with the arm and get it off the slide. This arm is attached to the lifting mechanism and the window motor. It's big and all comes out as one piece. That's the easy part. I have taken these things apart to see why this is such a common problem and it looks like the weatherproff sealing grease gets on the brushes and commutator of the motor and shorts out the motor. Theres just a bunch of black stuff in there. I cleaned it and put it back together with no improvement. So you will be needed a whole new motor and assembly. Good luck with the junkyards because this has happened on every jimmy I've owned and all that my friends have owned. I got lucky twice at the yard and found blazers that already had their motors replaced and worked good. But if you get one there have them hook it to a battery and raise it up and down a few times. Sometimes they work for a while and go out quick, plus most yards do not refund or exchange on any electrical parts. So that leaves the dealership and the parts store. Dealership probably wants way too much and I bet you can order these at any parts store also. I do not know how much they are but can't be more than 80 bucks. Good idea to take one of the plastic door panel snaps with you to get more. Now installation is opposite or removal. You can either re-revit or bolt the motor back in. You may have to tape the platic back in as the sealing goo is probably hard or worn off. Easy peasy, there you go. You probably just save 200-300 bucks over have a car place or dealer do it. Good luck!
