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

Do you have a voltmeter or 12v test light?

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

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?

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"... ;)
