I have searched the forum as thoroughly as possible for months now looking for an answer to my problem but am still stuck... I have a 2000 Pontiac Bonneville SLE and am currently without power controls on the driver'* door. Having searched everywhere I am finding that my situation is different from most since all buttons work other than the driver'* door... I have tried many things so I suppose the best way to start this is by posting a breakdown of my situation and what I have tried... My situation is as follows:

First problem - Originally all power controls were not working.

I solved this by tearing out the enter interior and found that I had some major leaks from each sunroof drainage tube, enough to where i had a good 2-3" of water when I tore out the carpet. Corrected the leaks and then corrected the corroded brown wires by replacing the splice that connect all the modules. This gave me power to my other windows (passenger front and back, and drivers back).

Second Problem - With that said, the lights on the drivers door switches work but I get no functionality from any of the switches (windows, mirrors, or locks).
- I replaced the driver'* door module but that did not fix the issue,
- I pulled all fuses and verified that there were none blown (for both fuse boxes) - still nothing,
- "jiggled" all wires while someone pushed buttons on the drivers door - still nothing
- Since the passenger side front door power locks button works I tried switching it with the driver side power lock switch in hopes that maybe my switches were just fried on that side but when I did that the driver'* power switch worked on the passenger'* door and the passenger'* power switch did not work on the driver'* door - thus affirming that either a connection is missing or something...

I am at my wits end trying solve this problem... I am not sure if there are any other mission critical splices/connections like the brown wire one already corrected but if there are I haven't seen anyone post about them... Also, I did see some posts about a grounding issues but was not able to figure this part out to know for certain that I completely tested the possible fix...

I am not an electrician but I am usually handy at troubleshooting these issues but this one has me stumped and work has me going on a 8 hour road trip on the toll road so I desperately need my driver side window back... can anyone give any guidance/suggestions on what to check?

check for 12v at two orange wires pins c3 and c1 with plug removed from ddm they are from different fuses. to check the ground put your meter on a good clean ground, verify continuity by measuring ohms to a different point, if it reads 0 it good then put one lead on the black wire of the ddm plug should read 0 there is also a black with white stripe test that for 0 as well

Doesn't each door have its own control module that talks to all the other doors via the data bus? And doesn't the 2000+ B-villes have data/ground issues under the back seat because of water?

Did you replace the door module (not the switch, but the control module inside the door panel) with a new or used one? If used, that could still be the problem.

The most likely culprit is the ground and electrical connections under the carpet under the driver'* seat. Pull the seat (4 bolts, T55 torx IIRC) and the carpet, and clean everything in sight. I know you did some of this already, but I will pretty much guarantee you missed a corroded connection, or bad wire, that is causing the problem. Make sure you pull all the wiring out of the plastic conduits to inpsect thoroughly. Use dielectric grease liberally in all connections to keep water out.

And ... fix the leaks.

first let me just say "wow" and thanks for the quick responses. I figured posting this first thing this morning wouldn't end up with responses for a little bit. Second, sorry for not responding until just now.

jwfirebird - I will check into this. I am currently at work but I will give this a try as soon as a get a chance this morning/afternoon...

Mike1995 - Each door does have a module and my understanding is that they communicate to some level via the brown wires (which are a huge culprit to corrosion. I fixed the splice and the other three started to work again. As for the grounding issue, I have read some stuff on this issue but am not certain that I was testing that piece 100%. Given the age of the posts I found i figured it was too late to "chime in" for an add response.

2kg4u - I reluctantly replaced it with a new one, also would the switches light up if the module was bad? Also, wouldn't a bad driver'* door module impede the operations of the other modules or do they not function in this manner? Also, I believe the leaks have been fixed... fixed the drainage tubes about 2 months ago and haven't found any water inside the car.

The driver'* module is a "command center" for the other three doors, and yes, a bad driver'* module can affect all the other doors. Since you replaced it with a new one and the other doors have no problems I am betting on a problem in the wiring under the driver'* seat. You may have fixed the leaks, but you may not have fixed the issues the leaks created.

Ok... Checked the wires for continuity on both orange and black sets of wires.. All register a 0... I do have a third onager wire on the ddm that registers zero that is right beside the other orange wire on the plug with 20 pin spots... Is this supposed to register anything? I am in the process of checking the doors wires for breaks but fired I'd post the result of the continuity test in case it points to anything specific...

Well no luck... Couldn't find any bad wires in the hinge area... I'll have to continue my work in the morning...

you are supposed to have 12v on the orange wires, and it may have blown the fuse in the meter if you try to check resistance on power wires. so check the battery or something with it first to make sure its working

Solved:
My 2001 Bonneville lost power to door locks, trunk, keyfob and alarm. Power windows and mirrors work fine. Had to manually unlock with key. The keyfob did work, because the headlights flashed. Doors, trunk would not unlock. I checked fuses, relays and wires, all good. Door controller worked because windows worked. The yellow wire to the door lock had no power. All my wiring checked fine. Finally found a wire diagram that led me to the Rear Integration Module (RIM) behind the rear seat. Replace it with one from a wreck and everything was back to normal.
Rear seat removal:
There are four clips at the top, 2 on the backside of each side headrest, Slide a screwdriver along the back, feel for a clip and depress the clip from the top. The headrest should pop forward a bit.
Do all four and move the seat belts to pull the back cushion forward. The RIM is on the driver side.
