Window Indexing Problem
Sometimes when I open the driver or passenger door the window does not drop like it is supposed to. Hence, when you try to close the door it jams.
Has anybody experienced this problem? If so, did re-indexing fix the problem?

A little more detail. 
Do the resetting of the window indexing for both windows after reconnecting the battery.
Close the car door. Raise the window and hold the up switch an extra 3 seconds. Release. Without lowering the window, hold the up switch again for 3 seconds. Release. Done.

You have to sometimes get a good relationship with Service Manager and write-up person and they will help you. I have a knowledge of cars and it has helped me because I have basically troubleshot all my car problems and have been right, they respect my knowledge and help me out.
I have been lucky, I have indirectly had write-up guys fired because they tried to B/S me in front of Service Manager and I called the write-up on it. Service manager was right there and heard consversation and write-up guy was gone when I returned two weeks later. These guys just can't play it straight, tell it right OR go find out. I feel sorry for all the people who were misled by them.

I'm probably just stating the obvious, but make sure the window is all the way up before exiting the car. If it's lowered even just a little, it won't index when you open the door. I just had it happen last week.

So as I leave work, I go out to my car and think "What the hell. I'll try JimTN's suggestion about holding the switch up for 3 seconds extra. Didn't even touch the battery. Problem fixed! Thanks!

will this work if window won't index back up? Passanger window will index down when opening but will not index back up unless lifting button to roll window up.
I just tried it - it does.

window indexing issues
This is why I love this forum too! Great people, great info!
Had the same problem just start this morning. I'll have to try the fix out later.
However, does anyone know WHY this is happening? Why does the solenoid or servo get freaked out?
Especially for some of you that seem to have this as a re-occurring problem.

it worked
I did not disconnect the battery.
Got int the car, turned it on, put the windows up and held the switches for about 3 to 5 seconds, let go and then held the switches up again for 3 to 5 seconds.
You could almost hear the solenoid reset. It was a very faint click.
Windows back to normal!

It seems to be a very persistent idea here that disconnecting the battery will "reboot" something. Nope. All settings except the window indexing position are in non-volatile memory. Disconnecting the battery does nothing. I'm guessing that the window position sensor is critical enough but also not reliable enough so the engineers knew window indexing would be a routine maintenance item. Therefore it was not kept in non-volatile memory to reduce the number of writes. There are a limited number of writes you can make to non-volatile memory before it dies.

dead battery
Battery dead. I tried charging it overnight, nope didn't charge. Jumped it
right off, drove about 60 miles. DIC reading 14 volts. Still no charge.
I was afraid to disconnect battery for fear of having to reset everything.
When I changed out battery (had it out 2-3 hours) I found out all I had
to reset was the WINDOWS. The tire presure all read 0 psi, but came
back on its own.
Forum is great, I learn so much here.

I love this forum.
My car has randomly been doing the window indexing problem over the past few months and it was scaring the crap out of me. It seemed to always fix itself, by itself, if I gave it some time.
Well yesterday it did it and had all damn day to fix itself and it just wasn't doing it.. And since I have a phobia when it comes to electrical I was more than scared now.
But then I searched on Google and came across this post and found the solution which worked for my car. Last night when I got home I had to leave the window down on my car in order to close the door since it wasn't indexing. I wake up about 30 minutes ago to it raining outside.. A bit of water had got in the car, not much thankfully, but more than I want in any of my cars. I knew I had to find the damn solution fast.
And here I am very happy at 2:53 in the morning because I found the solution and am now able to keep the rain out. Thanks allot to everyone that gave the answer on this thred. You guys kick ***!
