2006 GMC 3500 loss of power to drivers door

Power windows don't use fuse's , has circuit breakers
• PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
• PWR WDO CB 25A (IP wiring harness junction block) (System power for RF and RR windows 4-door vehicles)

Door Lock System Components
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)

Sounds like 3 different problems. The power door lock motor may be bad. Can you hear the motor trying to work? You will need to take of the door panel to test it and look for a bad connection. With the panel off, you can check to see if the switch is sending current to the motor. As for the rear door, It sounds like the manual linkage that locks and unlocks the door has come off. Again, with the door panel off you can test the window motor by giving it 12 volts.

I guess it's just me, but, I don't like taking battery cables loose. I know sometimes it works.
Did you check voltage at proper fuse circuits, use a testlite.
You may have to check proper wire colors in wire harness on hinge side of driver door. You open and shut the driver door so much, sometimes those wires break. I'm talking voltage and ground. The info I looked at was for two door version.

Hi there:

Recall for the Saab 9-7X: power-window and door-lock switches

Make: SAAB Model: 9-7X

Model Year: 2006-2007

Manufacturer: General Motors LLC Mfr\'s Report Date: AUG 15, 2012

NHTSA CAMPAIGN ID Number: 12V406000 NHTSA Action Number: EA12004

Component: VISIBILITY, POWER WINDOW DEVICES AND CONTROLS

Summary:
General Motors (GM) is recalling certain model year 2006 Chevrolet Trailblazer EXT and GMC Envoy XL and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, SAAB 9-7x, and Isuzu Ascender vehicles, originally sold or currently registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. Fluid may enter the driver\'s door module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.

Consequence:
A short in the circuit board could lead to a fire, increasing the risk of personal injury.

Remedy:
The remedy plan is still being finalized. A notification schedule has not been determined yet. Buick, Chevrolet, and GMC owners will be notified by GM. Buick owners may contact the owner center at 1-800-521-7300, Chevrolet owners at 1-866-694-6546, and GMC owners at 1-866-996-9463. Isuzu owners will be notified by Isuzu Motors. Owners may contact Isuzu customer service at 1-800-255-6727. SAAB owners will be notified by SAAB Cars North America and for inquiries, owners may call SAAB customer service at 1-855-880-0808.

Notes:
GM\'s campaign number is 12180. Owners may also contact the National Highway Traffic Safety Administration\'s Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1-800-424-9153)

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Fuse #10 in the rear fuse panel

I assume you are talking about the controller on the driver's door. The Driver's Door Module is likely defective. For troubleshooting purposes, you can swap in the passenger side module to verify.

{: ) Try checking the DDM fuse 10 amps at the rear fuseblock. If you'll be able to access the connectors under the driver door switch, check for 12v power by probing on all the orange wires. Check also the black wires for good ground connections. If the windows can be operated on the driver's door switches, then the door lock actuator coud be faulty. But if most or all of the buttons on the driver door switches doesn't seem to function at all, despite 12v power and ground on the respective terminals, then it can be a malfunctioning driver door switch. A new driver door switch will also require programming.
If ever this is the case and you need to be sure, you can try swapping the driver door switch from another vehicle you know of with a similar configuration as your vehicle.

Yes if the lock switch is bad then you will loose control of the other windows. The switch is easy to replace and is available at NAPA parts online or your local NAPA parts house. This is a common problem with drivers door controls on gm vehicles.

It is likely that you have a loose connection at the sensor somewhere between the sensor and the computer. Start by checking the terminations at the door sensor, and if they are tight, use a ohmeter and check the contact resistance for the switch in both open and closed positions. It could be that the switch is shot.

I have a similar problem. The remote sometimes opens all doors, and other times it will only open the 2 rear doors. Once inside the vehicle, the driver side window controls intermittently operates all windows and doors. It has no effect on the 2 rear doors, as the window controls still work. This behavior happens intermittently while driving the vehicle.
