Trouble with passenger window: '05 EXT Trailblazer
Passenger window will not roll down. Button on neither door will work to roll it down and I cannot hear the motor even trying to roll the window down so I'm hoping it may be the motor.
Anyone have any experience with this type deal? What do I need to look for to start troubleshooting? If it is just the motor, would you go ahead and change out the entire regulator?

Before changing the motor out make sure you are not getting any power to it, I had an astro van that one of the wires in the drivers side door broke and the passenger side window would not work from either button. It could be a bad switch in the drivers door or a bad wire, or the motor itself. The motor is the most expensive thing so check all other possibilities first.

So come to find out the motor and regulator are fine, cannot find a fuse that is no good anywhere. From what I can tell, the switch for the driver's side module is not working to the passenger window. Anyone know a good way to double check?

Well my wife has a '99 Lumina and my son has a '98 so I just swap them temporarily, doesn't help you any though does it? You are on the right track though, my son's drivers window switched messed up again to I had to fix it. I'll try and explain this so it makes some sense.
Each drivers door window switch is a DPDT switch, Double Pole, Double Throw. On each of the two poles of the switch there is a NC and NO contact (Normally Closed, Normally Open hence two "throws") When you press the button to open the window the "NO" contacts of the switch close and the "NC"s open. The drivers door switches are the "Masters switches, if the driver operates a window switch none of the other switches can work. The other switches go through the masters and rely on their NC contacts to pass the window motor current. In a nutshell I believe one of the NC contacts on the drivers door switch for the passenger window has failed. That make any sense? |

There is a recall on the door switch module. Not sure if it applies to 2005 or not, but you might want to check that out.
edit: just noticed you're in Altoona -- I'm originally from State College

The window power circuits usually have a circuit breaker instead of a fuse for overload protection. I've seen them fail before and they can be in odd locations.
On my Tahoe for example, they're small silver boxes hidden in a junction box above the drivers left foot.

It is a possibility. I'll post a picture of what I've worked on, probably similar. The switch tops have a catch on either side in the middle, they all need to be pried off. Most of the little catches are broken on my son's since I've done it twice but they still will stay on enough. Once you have all the rockers tops off you can pull out the white bottom portion and then pull the whole module out of the black casing. Then each switch rocker can be removed to access the switch contacts. Pay close attention to the location and orientation. I was able to clean up the contacts on my son's and get it working. The drivers window rocker had one of the little spring loaded nibs worn down, filed a point back on it and stretched the little spring a bit and swapped that rocker for a back window one that doesn't get used much.

Welp...update: There are no actual switches on for these windows. The windows are controlled by modules in the doors. I thought I narrowed down my problem to being a faulty passenger door module. I showed power to the module but nothing coming to the motor wires whenever pressing up or down on the windows. I replaced the modules today with another one...no dice. What am I missing?

The recall was on 2006 and 07 models.

Every other window works from the driver's door except for the right front. Perhaps the DDM not communicating properly with the passenger door module?

You say you changed the passengers module. How about the drivers module?
