I have a 2005 gmc envoy and the driver door module is not working windows cant go down

Check the fuses and switches with a test meter. It says you are 'Auto Repair'?? Click the images tab.

The BCM is located under the rear seat on driver's side next to fuse box.
Don't believe this is a BCM problem, it is more likely the Driver's Door Module itself. Try moving the passenger door module over to the driver's side and see if that works the windows.

The power windows on your vehicle are controlled by an electronic control module , as are the power mirrors !
Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)
• LR power window switch
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left rear window)
• RT DOOR CB 25A (System power for right rear window)

Your best bet , take your vehicle to a qualified repair shop.

Do you know anything about automotive electronic's , control module's , using a factory or professional scanner to communicate with said control modules ? Here is a list of componets involved in controlling the power windows ,lock's , driver an passenger door mirrors .

The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)

I don't think the switch would be the problem , more then likely broken wire's inside the flex boot from the body to the driver's door . See this more often then the switch going bad . Just replacing parts could get expensive . I would think a power wire or a communicate network wire broke .

Check fuse #10 in the rear fuse panel, if it is OK, the problem could be a bad Driver's Door Module (DDM) or a break in the wiring harness that passes between the body and the door.

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.

The power locks have absolutely nothing to do with the power windows - totally different circuits.

The FIRST thing to check is to make sure that the window lockout button on the driver's door control switch is not turned on. This will keep all of the windows from operating except the driver's window.

Other than that, there are several things that can cause a power window to not roll down. It can be a power window lift motor, a window regulator, the window switches, or any of the wiring in between. Also, you did not mention which window is not working. BOTH of the FRONT windows are equipped with Door Control Modules (DCM) which, in turn, are controlled by the Body Control Module (BCM). If it is the front window you are talking about, it will be necessary to scan your BCM for fault codes to determine the source of the problem. If it is one of the rear windows, this can be checked by regular electrical testing and a scanner should not be necessary.

There are different layouts for fuses depending on the model envoy you have and the engine size also. I can tell you this, it is always located in the rear fuse panel (see picture of location below) and the fuse will be marked DDR (drivers door module). It is in the number 10 position but like I said the layouts are different (nothing is simple). I went on and gave you a layout for the basic model of a 2005 so you can get the idea. I hope this helps you and good luck.

need to remove door panel and test power , motor, connections and track

it could be a fuse.
