OT Haunted Chevy Suburban???
Posted by: bought1 ()
Date: November 06, 2017 05:23AM

I have a 2005 Chevy Suburban that I use for my business. Only two people have keys to it....me and my field crew chief. For the past three weekends in a row, we have parked it in our lot, made sure it was secure and locked it up, and for the last three Mondays we have come to work and the driver's window is down but the truck it still locked. All other windows are up and the truck operates normal otherwise. The first two times i thought my crew chief was playing a trick on me, but this past weekend he was out of state (with the keys) and I had my set at home. Obviously this is some kind of electrical/mechanical problem with the power windows. Where to look first? Thanks!

Do they work with the key off or do they need ignition switch on?

If they work with the key off it must be the up down switch or motor.

Not a Ghost, but a Poltergeist! smileys with beer

Pretty sure that requires the ignition on to operate the windows, eh?

Better call the On-Star Ghostess and ask her!

My guess: The driver's door master switch (actually a computer called the DDM, Driver's Door Module) is failing. I just replaced that part in my 2005 GMC.

Dorman sells them rebuilt for $130 exchange. They're really specific to your vehicle's options you have to get one that matches your rig's configuration.

Add to above: The BCM is also a possibility because it can control items on the network. Still sticking with the DDR as the first choice though.

With what Craig said.....
the Passenger door module (which is the entire switch assembly) failed on my 03 GMC and it was like it had a stroke:
It lost all functions on the right side door (power windows, power locks, dome light operation) and the radio would not stay on after shutting the engine off. I think the LED arrow in the outside mirror was the only thing that worked on that side.
When diagnosing it I was going to attempt to borrow the switch assembly out of a buddies 02 and that had conventional switches with no integral module.

Windows only operate with the key on. Now I know its nobody funning with me because it happened again today while we were all at work and the truck was locked with windows up!!!eye popping smiley

I will see if there is anything obvious on the Driver's Door Module.

I also just replaced the heater/ac switch on the dash because it stopped blowing air... replacing the switch did not fix it. Either they are coincident problems or an exorcism is required!grinning smiley

Craig replies: I doubt you will find anything obvious and note that the DDM is powered at all times.

Since the mid 90s all my GM vehicles would still operate the windows and radio after shutting the ignition off for a few minutes or until a door opens, there is apparently some kind of timer involved or computer program.

Note the big power and ground connections (orange and black wires) closest in the picture of the DDR. Everything is hot all the time in GM serial bus (and later GM Lan). Switches are controlling signals, not power or ground. GM single wire serial bus is known for odd 'faults'.

Inside the DDR (happens to be a similar 2005 GM DDR module). Power and ground in and out to the motor are the big, copper terminals.

I should note in the above (1st picture), the power and ground wires (orange and black) are present, but I had already removed the big wires that went to the window motor for my project.

It could be the key fob is going bad. When I had my 2003 Chevy Trailblazer, I
could lower the windows by pressing holding the unlock button for at least 2
seconds. After having it for 10 years, my trailblazer experiencing similar
symptoms as your Suburban. I would lock it by pressing the lock button and
would go into a store. When I came back, all 4 windows would be down but the
vehicle would be locked. It took me a while to figure out it was the key fob.

Go under Settings, Vehicle, "Remote Lock, Unlock, Start", Remote Window Operation,
and Select OFF.

I can't edit my post above, but these is the wrong menu options. I remember
now that I had to go to the dealership and have them disable this feature.

Also, you might try changing the battery on your remote keyless entry and
resyncing, but that didn't work for me, I had to have this function disabled.

But just for grins, go out to your Suburban and press the unlock button twice,
then hold the unlock button for a few seconds and see if the windows roll down.
This had been a hidden feature (not listed in the owners manual) on automobiles
for quite some time and I bet this is your problem.

To add to electric mysteries...

My wife's 2011 Suzuki SX4 w/6spd manual has a problem of unexpected locking of the doors while parked and no one is around.
This can be exasperating when you leave your keys inside the car on the console... eye popping smiley
I think the key fob's battery could be the answer to this one, too.

I worked at a Suzuki dealer. When they quit selling cars in the U.S. the dealership owner offered to sell me any car in stock for less than his price just to clear the lot. I still didn't buy one!

We own two Suzukis, the '11 SX4 and an '07 XL7. No real problems in the three years that we have owned them.
The '11 my wife basically inherited as a 46K mile vehicle. It's been a trouble-free gas-miser. She's driven it about 45,000 since she got it.
Bought the '07 off a dealer for the price and < 100K (looks like the timing chain had been previously replaced).
We've put about 28,000 on this one so far. It's used primarily as a winter vehicle with the AWD.

I'm not that much of a Suzuki fan, but my wife is happy with them. And I have to admit that the little one with the 6 speed can fun to drive on occasion!

Many aftermarket alarm systems will automatically/randomly lock the doors too.

Just watch the workers at the car washes make sure they take the keys out...they have much experience!
