2001 Pontiac Bonneville Electric issues

I have a 2001 Pontiac Bonneville SE. I think my wiring might be going bad as my electronic door locks are malfuctioning on the rear doors, my door ajar sensor keeps going off even when all doors are shut, my rear window goes down on it's own sometimes. My CD player also malfuctioned and lately my radio turns off as soon as I shut off the car, which it did not do befor, and the most recent being my interior lights did not go off once the car was in drive and my headlights did not "flicker" when I used the remote. Can anyone give me advice on how to fix these issues?? The car also has a leak that we cannot locate, only the back left floorboard gets soaked when ever it rains and now the lid of my trunk floods as well...any ideas??? We know it is not the moonroof or any of the door seals.

    I have a 2001 Bonneville SSEI with 108k miles on it. Intermittantly/randomly the car goes "Ding, Ding, Ding" and the "Right Rear Door Ajar" or "Left Rear Door Ajar" messages appear on the Driver Information Center, then disappear. Sometimes the interior lights come on with them, then turn off. Sometimes it happens repeatedly one after another, sometimes not for several minutes before it happens again. Also intermittantly, the rear windows will on their own go down (sometimes a crack, sometimes all the way). Now, the oil pressure gauge is pinning at 120 when the engine is running. Someone suggested it might be the "Control Module" going bad. Can anyone lend any thoughts/suggestions? Please respond to geodouglas@aol.com. Thanks, George Douglas, Levittown, PA8t

My 2001 Bonneville only 1 window works the drivers side. I know all the motors are good . What could it be?


Terrell, some of the wires may be pinched or may have broken over time in the bundle of wires that go through the driver side pillar and into door from constant flexing of opening and closing door. I believe the master switch on drivers door is where the power gets sent to the other window controls. In the links below, some talk about moisture getting inside the plug to a controller for the windows. Check the attached links,instruction and guides, Good luck

How to remove passenger side door panel. On a 1999 Pontiac Bonneville SE.


I am not giving exact advice on your vehicle, but door panels usually arent too bad. Look carefully with good lighting all over the door panel for screws, which sometimes can hide well. Especially check down in the valley where you grab the door to pull closed. Sometimes those get forgotten. Remove screws. If you have never removed one before, there will be plastic push clips holding the remainder of the panel on, which you have to carefully pry away frum the door. One more caution, if the door has carpeting of any kind, those screws hide very well in that also so look good. Be very carefull when prying on door panel in case of a missed screw and beware of wiring for electric windows and mirror anjustments if equipped.

Can't figure how to remove right rear door panel on 2001 Pontiac


These are bad about those Cable operated window devices .. If it is bad get on ebay and get one ordered its your best bet.. Just take a flat screwdriver and go around the bottom of the door panel and pop it loose and up the sides .. there might be a hidden screw or two in the middle around the handles.. good luck ..

Major power window problems. 2000 pontiac bonneville


I had this problem where only the drivers door power equipment works.

It is caused by a splice under the driver's seat. Spice #S302 where the input from the drivers door module to the other door modules connects. It is one of those cheap *** splice that should be outlawed. Moisture gets in it and corrodes. Cut back the wires till you get the good stuff and redo it the right way.

Splice S302 can be found under the carpet about six inches before where the wires go up to the drivers seat. It is in a plastic wrap and tape. I believe the wires for the window are brown and white.
