Anyone have the window not roll down? The others do just fine and the fuse looks good. Any ideas as to where to start?

 

Do you hear a clicking or grinding sound? May be off the track

 

No noise at all, kinda like no power to the motor.

 

I had something like this happen to me a long time ago when I owned a (cough cough) vw. The power window motor failed and the dealer replaced it for me since it was under warranty.

 

I just also realized the power door locks no longer work also. Anyone know if the fuse block under the dash is the only one? Cant find the accessory fuse. PDL and PW fuses checked ok.

 

If the PDL and PW fuses are good, then there is no need looking for anymore, as those are them..You may have a wiring problem going to the door, since both the Lock and window are affected.

 

Had this occur on mine. Ended uo being the molex plug on the door harness fell apart. Dealer placed plug and fixed harness. It about a two hour job due to taking door pane off. checking harness. replacing plug. etc

 

It just happened when I disconnected the battery to install the intake. The daytime running lights dont come on either, but the headlights do if you put them in the on position. What is the connection between all of this. Hummer dealer hasn't a clue.

 

Yeah, it don't make sense to me either that just disconnecting the battery has something to do with this...Maybe a freak coincidence..Take a look around under the dash on the left side where the parking brake is..and see if any of the connectors under there have come loose.

 

Hummer dealer figures it out....this is a wierd one.

If something like this happens to you here is what you do.

Disconnect the negative and the positive on the battery. Then touch the cables together for 5 seconds and let them rest for 5 minutes. After the 5 minutes connect the positive and then the negative. Problem solved.

Have no idea what this does but supposedly if you disconnect the battery sooner than 15 minutes of shutting off the H3 off, then the "computer" doesn't have time to shut down properly. Just like your home computer if you just press the power button to shut it off. After 15 minutes the computer shuts down properly and there will be no problems then. However I disconnected the battery too soon and the computer didn't have time to shut down properly causingelectrical problems. Hopefully this will help someone along the line.
