In this video, we're going to show you how to replace the driver's front window motor on this 1997 Cadillac De Ville, same as any '94-'99. Taking the door panel is a little different. This will cover '97 to '99 as far as that door panel goes. The tools you'll need are a flat blade screwdriver, Phillips screwdriver, and a 10 millimeter socket and ratchet. Start by carefully disconnecting the negative battery cable and this should, on most vehicles, will be a 8 millimeter wrench. First, take a flat blade screwdriver, insert in the middle and there's a little tab. When you push on it this comes up, forward and out. And then this back one, there's a little tab here. Just work your screwdriver in there lightly. Pull that out. And this one here, push on the tab. Pry up and off. Same thing here. Push on that tab. Pry up and out. Same thing here. Little tab. Pry it out. Then pull that connector out. Okay now here on this courtesy light, carefully pry the front of it out. There, it comes out. There's a little tab right here. Pull up on it like that.
Now you want to remove this panel here. You basically want to go in and find... you can pull it easy to make sure that the metal tabs don't get caught in your door panel in the leather and rip the leather. You can see this one's caught. Going to use the screwdriver, pry the leather right up over and out. Two connectors. Push a little tab. Disconnect that. And then on this little tab and underneath here, push it down. Disconnect that. Now there are two screws, Phillips. One right there and one right in here. When you got for this one you want to have your screwdriver slightly angled. It's not straight in; it is at somewhat of an angle.
I'm just going to fast forward as I'm just removing those two Phillips screws. Once you remove those screws, lift your panel up and off and reach in behind and disconnect the speaker. Now you want to carefully pull down your water shield. Notice I carefully pull the back to front. I really only need to pull the front part back and expose the window motor. Here's your car window motor. It's held in by three 10 millimeter nuts and there's a lead. Just press the tab back here, pull the lead out. We'll fast forward here as I just remove those three 10 millimeter nuts that hold the power window motor. Then you need a screwdriver and pry the motor right off. There's nothing wrong with our original motor and I'm not one to waste a good part. Re-installation is very straightforward. Just push the motor on. Insert the three nuts.
Just a quick note here. When I put this motor on, the motor pushed all the way nice and flush to the door panel. If your motor goes on but still has a quarter of an inch before it will go against the door panel, that means that the gear is not meshing. All's you want to do is put the three 10 millimeter nuts on, tighten them down very lightly, then reconnect your battery, reconnect your motor and your switch and just run the motor and push that motor in until it meshes with the gears for the window. And then go ahead and tighten it up. We'll just fast forward here as we put on those three 10 nuts and then tighten them up. You want to tighten them up nice and firm. They don't have to be extremely tight, though. You can test it. Plug that in. Make sure you plug in your ... now you can plug in your switch before you put the door panel back together to test it. Now connect the battery. Okay, so the window seems to work correctly so we can take that switch back apart and then put our water shield back up into place.
To reinstall the panel, what you want to do is get your bottom three hooks in first. You just kind of place them close to where they go. Reconnect our tweeter. Make sure all our harnesses come in through here. Okay, our courtesy light back here. Then as we rotate up these two harnesses. Lift up on the panel. Push it in. Make sure it goes on in front and rear. Then push down. Make sure all our harnesses are out. I'm going to fast forward here again as we install those screws. Plug in our courtesy light. Back in place first. Hook these connectors in. Put this in. Hook the bottom in first. Just remember to reconnect your battery and you're all set.
