NO POWER TO ALL DOORS EXCEPT DRIVER SIDE??? HELP!
 

Thanks for any help you can offer. Around Christmas time all power to all doors except the driver side door stopped suddenly. One day they worked the next nothing. I thought it was a fuse but checked and it did not seem to be. There is a remote car starter in it and thought something suddenly went wrong there somehow and was interfering but no. It worked great before the problem and still works and was professionally installed before we bought the car. No locks or windows or even lights in the power door/window buttons work. A friend that knows quite a bit about engines/cars in general took the driver side door panel off and found power to be flowing properly at all points we checked. We followed wires under the dash over to the passenger side and all seemed fine. We did find a wire grounded to the frame under the plastic panel on the floor near the front of the driver door and when disconnected a few weird things happened, cannot remember all but starting the car without the key seemed to be one if I recall and lights on the dash went crazy, a few clicks here and there. Hooked it back up and all was normal again (ground or ? for the starter maybe?). I hesitate to take it in to a dealer as they like to spend all day working on it only to say we found nothing usually. I guess I could give them an hour or two and that's it, but have been charged for 8 hours diagnostics before and still not been anywhere. A dealer here in town seemed to think they knew what it was with me describing to them as they had another Bonneville or similar car with the same problem a month earlier and said the repair was $200-$250 but would not discuss at the time what it was. I would hate to pay that and find out it was a small item they have screwed me for as this is the same dealer that once charge my wife an hours labor (about $65 a the time - now over $85/hour) only to tell her she had installed the wrong type of halogen bulb in the headlight!!! We do not have much money to work with right now, things are tight. Someone mentioned a control module in the driver door that controlled the other three doors but everything looked to be in order. We must be missing something. Thanks again for your time.

I looked at a wiring diagram & can't believe what a complex system it has to control windows & door locks. There's a module in each door, three 10 amp fuses & a 30 amp circuit breaker. The fuses & circuit breaker are all on the "rear fuse block". Are these the fuses you checked?

The fact that the lights are also not working has me wondering if you have a bad ground. Earlier years have a ground buss between the front seats & the door sills. Can someone confirm if the 2000+ has the same setup?

When I bought my car...I had the exact same problem. Here's my non-technical description:
Corrosion... previous owner stored car ... there was green corrosion on the main wiriing harness where all wires come together. The cleaned it up and it's been fine since (nearly 30k miles later).

EDIT: I think it was the main module in the driver's side that runs power to the other mods...?? Maybe??

Harness?
 

Harness under the hood or in the door panel? Sorry!

Are both doors on the driver's side getting power or just the front drivers side?

Just the drivers door, nothing else. Everything works normally on the drivers door.

A few more questions and we might be able to narrow this down.
How many lights aren't working?
The windows & locks on the other three doors don't work from the drivers door or from the switches on each specific door?
Do you have a voltmeter or 12v test light?

Re: Harness?
 

I'm thinking that mine was in the drivers door panel...but I do recall them saying they checked everything... I know they took out the back seat cuz that was not put back correctly. I remember them saying that the place on the driver's side where all the power to the other three doors meet was corroded. :roll:

I'm sorry I can't be more specific...but I can say that your symptoms sound identical...no power anything to the three passenger doors. Only to the drivers door.

The driver door control module does communicate with the other three door control modules through serial buses. The 30 amp ckt bkr in the rear fuse block is power for all power windows. So based on that, the 30 amp ckt bkr is not tripped (driver door power window is operational) There are three seperate 10 amp fuses: one fuse for the driver door control module, one fuse for the passenger door control module, one fuse for both rear door control modules. This is control power for the door control modules and power (batt positive) for the door locks & the front door side mirrors. The door control modules switch power & ground for all functions in a particular door. the 30 amp bkr supplies power for all power window operation. The driver door module is more or less the central control point for all other door functions. I assume that you have no local control of anything at each door?

Mark - I agree with you that power must be coming through the 30 amp breaker. It also seems unlikely that 2 of the 3 10 amp fuses would be blown. Plus the power for the light in the passenger door lock comes from another source. This is what makes me suspect a bad ground but I'm having trouble believing the rear drivers door shares a ground with the passenger side doors. Does your factory service manual show where the grounds are? The wiring diagram I have shows the light sharing the same ground as 1 of the 3 front passenger door module grounds. This ground wire is shown going to the "air conditioning & seats system".

The lights in the door lock/window controls on all doors but driver side are not lit. The power window and the power door lock buttons are usually lit up when the lights are on (noticable only when driving at night of course) and they are not lit at all. When I hit the lock button on the driver side only the driver side locks, not the rest of the doors. When I push the window button on the driver side the driver window functions fine, when I try other windows from the driver side controls, nothing happens to the other windows. Neither the driver side window/lock controls or each respective individual control buttons on each passenger door work to control the lock or windows on those doors. Which is what I meant when I said no power at all seems to reaching those 3 doors. The light cluster on the driver door is lit up like a christmas tree and all functions fine. I cannot imagine any hardware in all three doors going bad at the same time so it must be a problem at the driver door. There was only one fuse that controlled doors windows under the back seat, I cannot remmeber the amperage but there was only one other of the same size so I switched it out and the features the other fuse controlled still worked so it did not seem to be the fuse. The manual mentions a MAXI-Fuse under the hood and to seek service if one goes. I May go into the dealer to have them check all fuses to eliminate that I guess but we were pretty sure none were bad. All other features in the car function fine, Air, Seats, Heat to seats everything. I do notice a slight clicking sound coming from behind the cluster of gauges when we start the car, seemed like an odd clicking to me when we first bought the car and sometimes when the car had been driven or is still warm, there is no click!?! I dismissed it at first because another SSEi we took out had the same click when we started it for a test drive. Thanks

Thanks Mark. No control at any of the passenger doors for any feature is correct

If you want to check this out further here's where to check for power & grounds in the front passenger door. After you get inside the door panel unplug the wiring harness(es) from the door module. Two of the terminals should have12volts. Both are orange wires, should be terminal #11 & terminal A. There are three grounds 2-blk/white 1-blk. Blk is terminal D. The other 2 are terminals 4 & 14.

Here's an option that doesn't require puliing the door panel. Find where the wires come through the door into the passenger footwell. Trace where all the ground wires go & look for corrosion at the connection. I should have asked this before. Have you ever had trouble with the carpets getting really wet?

Edit - If you PM with your Email address I can send you a copy of this wiring diagram.

Just a side note on the interior ltg. ground locations. All vacum fluorescent lamps and all incandescent back lighting lamps have voltage & ground at G200 and at G201. G200 is on the driver side under the carpet retainer at front left area of (the garnish piece that curves upward) footwell. G201 is same location on passenger side. Check those areas for corrosion. Also as for the door locks & windows, there are features that can be programmed through the Driver Information Center (DIC) that have an effect on how these operate. As an example, your window lock switch can be configured through the DIC to lock out all windows except driver window. When you shift out of park do the doors automaticly lock?

This is an electrical issue. Moving to Electrical... ;)

Huh.. i posted in this one saying dont dig up old post. where did it go..... :?:

You posted while I was "mid-split"... ;)
