Don it. Good half day for amateur. Get Chilton 86-99 Bonneville, 88, Lesabre manuel.. Tricky to find bolts are under end flaps on door close handgrips. Took me a day to figure that one out. Others under light at lip of back of door. Book indicates to strart with window 3/4 up if you can. Flip up window control at rear of panel. After all screws are out raise outer edge of armrest and look for notches 4" and 11-1/2" from rear of armrest to slide inward to remove. There are screws under the door handle too. Screws everwhere. When pulling bottom of panel from door lift with a notched bar to avoid tearing the fasteners out of the cardboard panel. Two screws behind seatbelt notch at top need to come out to allow positioning the glass. The panel at the bottom of the top opening can be removed for more fredom in positioning the glass when reinserting the ball in the lower track on the window. Tape glass with duct tape to keep it from falling. Drill the factory rivets that hold the old regulator and I replaced with stove bolts with nylon locknuts slotted head to the inside the car. Can't remember the size, probably 1/4 or 3/16". Remove speaker if in front bottom of door to use your hand to do work in the door. You must twist the regulator forward with window 1/2 down to remove the ball from the socket in the bottom sliding metal track at the bottom of the window. Don't drop the window after removing the socket, tape it in place. Don't know what you do if you cannot move it to 1/2 up position. By the way, the body shops say you must use rivets, not screws or it will shift, but I have had no problems with the screws for reinstallation several years old. The rivet they use take a big hydraulic pop rivet gun that you won't have. Good luck, I don't envy you. Need to do other window on my 91. The window control may not be the same on the Custom, mine is the Ltd. you may be able to remove the motor from the regulator in the door without removing the regulator if you can figure out how to get the bolts that hold the moter to the regulator. inside the door.

Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing.

Howto repair left back window


Get a tool for removing the inner door panel. Determine which tool is used to remove door handle / armrest (screwdriver or Torx or hex head screw) and get that tool. Remove door handle, then door panel. Once that is removed, you can determine whether nylon tape needs to be replaced or if motor assembly has come loose and needs to be reattached or if the window is simply off its track (if it is, you should already know this because it will drop down by itself). A video is at How To Install Replace Rear Power Window Regulator ...

If you want to have someone else repair the window, and if it has come off its track, use some clear packing tape (lengthwise) to secure the window to the door until you can get it repaired.

Follow the wiring from between the door and the body to the insides under the dashboard. It's usually inside a soft plastic or rubber tube for protection. Follow the wire bundle if you can to the fuse panel. I don't know exactly where it is on this car, but it's usually very close to the left and underneath of the dashboard. You may find that a plug that has all these wires together has come loose somewhere.

Please update here on your progress. Good luck!

1997 buick lasabre. How do you remove the front left door panal. The window does not work. When I press the switch I can here it click


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

99 Buick LeSabre, how do I remove driver side door panel to replace power window motor?


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

How do I remove the front door panel to replace the mirror


Normal 0 Disconnect your negative battery cable. Locate and remove the screws that hold your interior door handles in place (they may be hidden by snap in, or snap on clips). Remove the interior door handles, then disconnect the wire clips to the switches. Your panel is held in place by snap in clips; use a small pry bar to pull them from the door (try to get as close to, or directly under the clips to prevent them from tearing out of the door panel). Once the clips are pulled, pull the panel upward to remove it from the door.
Install in reverse.

If you don't have power windows you will have to remove the manual window crank. It is held in place by a clip on the back side of the base. To remove the clip, you will need a small hook (kind of like a knitting needle). Put the hook in behind the base, and grab the clip and pull it off. To replace it, slide the clip back on the window crank, and snap it back on the door.
