Remove right rear door panel 2003 Buick LaSabre

In the trunk of the car there is a black panel behind the rear seat remove screws that hold this panel on. There are three magnets at the top of the panel. Remove panel and put screws in safe place. Go back to the inside of the vehicle there are three brackets that hold in top cover of back seat remove that lay it down in the back seat. You now have complete access from the rear seat to the trunk. To reassemble reattach rear seat top. Reassemble black panel in trunk just attach to metal with magnets and then put screws back in. Hope this is helpful and informative.

On the LaSabres they have a fuel tank pressure sensor and a fuel level sensor if either one has to be replaced they are built in to the fuel pump.You can get to the fuel pump by removing the rear seat and removing the panel to remove the pump.The fuel pump is located in the tank.

In the rear of the trunk you will find several plastic wing-nuts that hold the liner and the light housings to the rear panel. Remove these, pull out the housing, the bulb scockets twist out after releasing the locking tab [ push on lock to center of scocket to release ]. When reinstalling housings to panel make sure rubber sealing washers on the studs are there or water will leak into trunk. good luck.

yes there are bolts inside the door panel arm rest you have to take it off

the door panels will pop off the use body plugs, some models you have to unscrew armrest first take a flat screwdriver annd slide it behind panel and pop off section at a time

Make sure the switch itself isn't bad. Pull the power window control assembly. I think there is a clip in one end that you push and the panel pops out. The switches are interchangeable so just swap one of the GOOD ones for the driver's switch and see what happens.
If you have to remove the panel, go to O'Reilly's or AutoZone and get a door panel removal tool. This will pop the plastic clips around the door panel. You may break a few but replacements are at the Auto store also. If I remember right, there are 2 large screws that secure the armrest to the door. Might be hidden under a plastic trim plate. BE CAREFUL plastic breaks. Good Luck

You'll need to remove the door panel. Once you do that you'll see the electrical connections and the screws holding it in place. Disconnect the plug and remove the screws. THe mirror will pop off and you can install the new one.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
