Replace Left hand power window regulator on 1995 Saturn SC?

Answer 1

I just did this in a 1993 SW2 and I'm assuming that the door construction is relatively the same.

1. Remove the mirror. You'll need a Philips screw driver, a set of small Allen keys and a 10mm metric wrench. First remove the interior trim by undoing the screw and detaching the mirror adjustor (assuming manual here) using the appropriate Allen key. Next remove the insulation and detach the 3 nuts holding the mirror using the 10mm wrench being carefull not to drop the nuts. The mirror should pull off with a gentle tug.

2. Remove the exterior door skin. You'll need a Torx screwdriver . On the inside edge of the door you'll see a series of black headed flat screws that fit a Torx screwdriver and hold the exterior skin on. Remove these. Remove the door handle by lifting up on it and carefully pulling the 2 pins from the bottom. Next slide the door handle to the left and it should come off rather easily. Finally, remove the black window gasket where the door panel meets the bottom of the window. Do this by pulling up firmly on the gasket. Once this is removed the door panel should pull off with gentle force exposing the inside of the door.

3. Remove the interior door panel. You'll need a Philips screwdriver for this. First, detach the mechanism for the interior door handle and lock accessed from the exerior. There are little clips that you'll need to detach before you can pull the rods out. Now, from the interior remove the door handle and trim by removing the 3 screws and then sliding the unit forwards and prying outwards. Once complete, gently pull the interior door panel off by prying at the edges.

Remove the lower space frame supports on the exterior. You'll need a 10mm wrench. There are 2 rods held onto the door with 3 bolts that come from the bottom corners to the middle door support. Remove these.

5. Remove the power window motor and regulator as one unit. You'll need a drill, drill bits and a 10mm wrench. Drill out the 4 rivets holding the motor and regulator mechanism to the door. Undo the 2 bolts holding the lower regulator track. Carefull that the window does not fall down at this point. Finally, slide the wheels out of the upper regulator track that is attached to the window. This will take a bit of patience.

6. Install the new window motor and regulator using 4 x 10mm long bolts and locknuts where the rivets were drilled out and then reverse the steps above to reassemble the door.

In my experience I determined that there are 2 types of window motor/regulator parts. If the new one is not the same a the old then you'll need to reverse the upper regulator track attached to the window. This requires a specialized tool which you may be better off bringing the window into a auto glass shop so they can do this. There is enough room to drop the window out the bottom of the door by turning it sideways and carefully manouvering it.

Good Luck
