How To Do It

Step 1

Remove the door panel on the offending door

Step 2

After you have your door panel off, you will see a thick plastic covering that is covering everything on the door. This is merely held on by some glue, and can be pulled off.

Step 3

After that nasty plastic is gone, your door panel will be exposed. You will see a metal brace, a few holes (lower right and upper middle) and then a lot of rivets. About ten of these rivets are what are holding your window motor and regulator onto the car.

Step 4

Before your begin to remove any rivets, tape your window in the all the way up “position.” This way, when you do start drilling or punching out the rivets, your window won’t go crashing down and break.

Step 5

Now for those damned rivets. You will need both a ¼” and a 1/8” drill bit. You can also punch out the rivets, but drilling is far easier.

Step 6

Locate your window motor near the bottom right hole in the door. There will be a rivet at the far end (closest to the car), two closer to the middle (about 4-5 inches from the end), then there are three or so closer to the middle of the door that also need to be removed. There are five (I think) rivets holding the motor and regulator to the door. There will be 5 more rivets are holding on a large metal brace to the upper left side of the door. This brace needs to come off in order for you to get the motor and regulator out of the door. So remove those 5 rivets, remove the metal brace, and simply pull the whole assembly from your door. If you have trouble getting the assembly out the hole in the door, make sure that the arm attached to the window track is in the up position. So the assembly should come out and a near 90 degree angle.

Step 7

Now its time to separate your motor from the arm that moves the window up and down. There are a number of smaller rivets, not sure how many, that hold the arm to the motor assembly. Simply drill all these out with a drill bit that is larger than 1/8”.

Step 8

Take your new motor and rivet or bolt (whichever you have) and reattach the arm to the motor in the same position you took it off the old one. Make sure the gears are matching up that are on the motor and the arm. Lube everything up good with some grease.

Step 9

You are now ready to put your new assembly back into your door. To do this, once again make sure that the assembly is at a 90-degree angle, or as close to this as you can get. Fit the assembly back into the door.

Step 10

Once it is in the door, position the wheel at the end of the arm back in the track that attaches to the bottom of the window.

Step 11

Now here’s the fun part, reattaching the assembly to your door. You can either use bolts or rivets to reattach it (I used bolts because I didn’t want to have to deal with those damned rivets if I ever needed to change the motor again). Note: If you have some trouble lining up the holes, this probably means that that your arm that raises and lowers the window is too high. To fix this, plug in the motor, and lower the window a tiny bit at a time until the holes line up. Make sure your hold the motor while you do this.

Step 12

After you have your assembly reattached to the door, plug it in and test it. Make sure that it goes all the way up and down without any hitches.

Step 13

Reattach the plastic if you so desire, put your door panel back on, and enjoy your now functional window.
