Is the most common culprit the ddm? Or could it also just be the switches? How do I test? I have dvom and power probe. The rear windows work only by their own switches. Not the master switch. I took a look at it and I have battery voltage going to the ddm. Wiggle the cables a bit. Try wiggling relay 68 it might just not make good contact or is stuck. Pulling the fuse or breaker cuts the power and resets the circuit.
Good Luck and let us know how it is going. Get the four screws out and slowly ply open the master switch. Clean the upper circuit board with light acohol wipe. Look for brownish spots.
Drive off and everything will work normal again. Show 6 more comments. I thought that I heard this hear before but you disconnect the battery terminals and hold them together for 15 or more minutes then reconnect them. This has worked for me before but again I am having the problem and it's not working. Need help fixing it. So was replacing 3 of 4 blown out Speakers and left key on on last one opps dead battery After jump start no Driver window or Pwr locks..
Went on the old interweb found this page and did the Pwr cable thing for 30min. I have to agree with Bobby from above. This happened to me, checked all fuses, 8 on my truck, obviously I know its just my drivers side window and locks, but thought i'd check it anyway.

After disconnecting the battery, touching the terminals and checking the fuses with no luck, I tried this suggestion and it worked! I removed the unit from the door panel and removed the circuit board from its housing. After about 30 seconds of hair blower heat I heard a click. I reinstalled and my windows and locks worked once again. My issue started with a dead battery, so I don't know why this worked, but it did.
Thanks Duane for your input! I am actually blown away by this, I didn't think would work, but brought the whole housing unit inside from my 06 H3 and used the hair dryer for a few minutes, took it back out and plugged it and it works again! I recently had the problem with the driver window and power locks not working. Happened after battery died. Tried everything-unhooked cables for 45 minutes, clicked them together, replaced battery, checked lock default options, unplugged control unit, checked connections and wiring.
Still nothing. Finally tried taking it apart, making sure the connections were alright and buttons worked, then heated it with a heat gun for a few minutes. Didn't hear any popping noises but once I put it back together and back in Didn't expect it to Saves a lot of money I would have had to pay to get it fixed. After battery went dead on my H3 dash cam drained it , driver's window and door locks were inop after I re-charged the batt.
Checked fuse 8 and relay Both were good. Popped out driver's door switch assembly used thin screw driver on forward and rear edges-- clips are in those locations. Removed blue and white wire harnesses and heated switch assembly with a hair dryer for a few minutes.
Heard two loud clicks. Reassembled harnesses, turned key on and all systems were operational. Show 2 more comments. Press and hold the power door lock button until the DIC display shows the current door lock mode.
To view the next available mode, press and hold the reset stem until the mode appears. Release the reset stem and press and hold again to view the next mode. Once the desired mode is shown on the DIC display, briefly press the reset stem to set your choice. The DIC display then clears. Lock 1 default : On vehicles with an automatic transmission, this mode locks all of the doors when the vehicle is shifted out of PARK P and unlocks all of the doors when the vehicle is shifted into PARK P.
Lock 3: On vehicles with an automatic transmission, this mode locks all of the doors when the vehicle is shifted out of PARK P. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation.
The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM. The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows.
However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors. I am having the same problem. The clicking and working not working. Apr 19, What about the recall?
Just had my'07 Envoy DDM replaced free. They sealed it last year under recall number one, then sent a new recall to replace it.. Jan 5, Does that sound reasonable? Mounce Guru. Mar 29, 13, Tuscaloosa, AL. I don't get enough interest to justify the cost. Reactions: Mounce and mubai. Knucklehead Registered Member. Jul 23, When did these start needing to be programmed? I just had to replace mine. Tried the DDMs from my dads 07 and my moms 05 in my 03 and they all worked fine.
Ended up buying one from an 06 and works fine in my Brand new ones are not programmed initially. Used ones, obviously, already are. Usually we recommend people try to buy a used module if they can find one. Blckshdw said:.
