okay, I hope you used a trim tool to compress the sides of the plastic rivets, otherwise you can possibly damage the trim itself. (No need to panic, you're probably fine.) But I highly recommend spending the $5 on the trim tool.
Actually, pulling the trim is not the first step. But let me list the steps in order:
a) Trim Tool
b) Drill and 4.8mm or 3/16 inch drill bit.
d) Assortment of screwdrivers.
e) Torx bits (or driver) for electric motor mounting.
1.) Use a very small screwdriver to pop the hard plastic shell behind the door release handle. Use a large phillips screw driver to unscrew the screw behind it. Its probably very tight.
2.) Do the same with a small round plastic cover under the actual (big) door handle. The same kind of screw needs to be removed.
3.) The door has a small clear light in the bottom. Use the small screw driver to remove the light. Disconnect the two connectors.
4.) Use the small screwdriver to remove the window switch in the rear door. Gently, oh so very gently, use the screwdriver to release the clasps that hold the switch.
5.) With the trim tool, pull the lower part of the trim away from the door. Feel the plastic plugs with the trim tool, compress and pull them. Be careful not to damage the moisture barrier.
6.) Unscrew the door lock pin and remove it. Also remove the small plastic trim cover from the door lock itself.
7. )The top of the trim is held by metal clasps.
Gently lift the trim up. If you can reach, gently push up the horizontal part of the trim from below. Completely take off the trim.
8.) The door release cable is still connected. Disconnect it from behind the release lever.
9.)Now your should see just the moisture barrier. Gently pull it off. Be careful, it rips easily. Pull it just far enough to expose the regulator mechanism.
10.) Unclasp a small plastic clasp from where the window connects to the plastic slider of the regulator. Move the window slightly to the side until it unhooks, and push the window all the way up. (It should support its own weight in that position.)
11.) Presuming that the regulator mechnism took a hit and is responsible for the power window failure, take a 4.8 mm (or 3/16 inch) drill bit and drill through the 4 metal rivets holding the regulator. Drill straight through, and dont use any larger bit,or you may damage the door.
12.) Unconnect the electrical connector on the regulator, tilt the regulator and pull it out. Mine looked like this.
13.) Use the torx bits to remove the electric motor from the old regulator and transfer it to the new one.
13.) Install the new one by sliding it into place and push the new rivets into place. (I would suggest connecting the motor and the window to the regulator and testing the assembly at this point of time, before the rivets are set.)
14.) Use the riveter to set the rivets that came with the new regulator.
15.) Steps 9 to 1 in reverse.
Good Luck !
