Has this happed to you -Window indexing ?

[bee sting]

Has anyone had the issue of the door glass not working properly ? Yesterday i got back in the car and I noticed "Open, Then Close Driver Window" displayed on the DIC. Then tried to opened the Passenger door and the window was so out of place the door glass was hitting the pillar !
Called a friend thats a GM parts manager at a local dealership and he told me how to do reprogramming the window indexing . This just seemed odd to me that this happened . Anyone else had this issue?

OK so how did you reprogram it?

[KATHY63]

We have had it happen a couple of times but I don't remember how we fixed it.

Ok here is a few ways to do it ....


Follow these steps starting with step 1. If step 1 does not work for you, move on to step two. Step 1 should remedy the issue. If step 1 and 2 do not work, it's quite possible that the shop will need to perform step 3...which I won't post due to the fact they need to use a scanner on the car. ...ie: can't do it at home!

First, you may need to relearn or re-normalize IF....

1. The battery has been disconnected or replaced (winter storage may be a problem for some)

2. The door or motor harness has been disconnected.

3. Glass is out of alignment

4. When the door or door window glass has been replaced

5. When a regulator has been replaced



METHOD 1: (Use this plan!!!)
1-A. Open the car door which needs to have the window adjusted. Turn the ignition to the run mode. Do one door at a time !!!

1-B. In the door jam, release the harness from the door (with a medium screwdriver, pull up the release tab, pull off w/ the palm of your hand, and pull the harness off the door for a minimum of 60 seconds (this is very important as the memory will be lost).

1-C. Reconnect the door harness and lock the tab back down. Close your car door.

1-D. The DIC will ask you to lower your door glass.

1-E KEEP YOUR FINGER ON THE BUTTON FOR 4 TO 5 SECONDS ONCE THE GLASS IS DOWN. ROTATE YOUR FINGER TO THE UP POSITION AND HOLD FOR 4 SECONDS ONCE WINDOW IS AT THE TOP.

OTHER FUNCTIONS MAY APPEAR IN YOUR DIC BEFORE YOU ARE ASKED TO PROGRAM THE WINDOWS. This is normal

Window is now reprogrammed, Repeat to the other door glass.

However, sometimes the door glass regulator does not always relearn on the first attempt. If when you open the door and the door glass does not drop down to the open door position, your window regulator did not relearn or re-normalize...in which case, you are going to need to drop the glass back down, unplug the harness and try again. Yes, it can be picky sometimes and not want to work on the first time.

If Step 1 did not work, you may attempt this method. Also, if you made glass positioning adjustments, this might also be a fix.

METHOD 2:

2-A. Access the under hood fuse box and remove fuse # 26. Wait one minute and reinstall fuse. Close your hood.

2-B. Get inside car. Close both doors. Start the engine and follow the instructions on the DIC (DRIVER INFORMATION CENTER).

2-C. The DIC should instruct you to run the window down and up on both sides.

2-D. Verify that both windows have express up functions and no DIC message exists. If the DIC does not instruct you to operate the window to re-normalize, do the following.

2-E. With a 2nd person helping, pull the fuse while the window is in the downward motion.

2-F. The window will stop. Release the window switch.

2-G. Reinstall the fuse and go back to step 2-B.

My friend told me to do the indexing with the car door shut if possible and do the window switch up n down and hold for 3 sec. it was and do it for 2 cycles. worked for me

If this is like the Corvette line you can just roll your window down all the way and continue to hold the power window switch in the down position for 5 seconds, do the same this all the way up and hold for 5 seconds, and repeat all the way down. This learns the top and bottom position and your all set.

Mine does this from time to time on my passenger window. I get the notice on the DIC. The strange part is when it occurs the window refuses to move when I toggle the switch. I have to shut the car off and then on a few times and then it begins to move. I follow the re-index procedure and it is fine.

It has now happened three times in a year and a half. Has anyone else had the issue of the window refusing to roll down when they get the re-index notice?

Very strange...

[2010SLVRBULIT]

same problem here when had the hood up for a few days..

[bee sting]

Mine did this while I was installing my headers and the frontend was on jack stands.

I had this message appear last night for no apparent reason when I got in and started the car the message appeared on the DIC. I lowered and then raised the window and the message went away. This is the first time I have had this happen.

Yes This is what the glove box manual says.

There is absolutely no need to disconnect anything or to pull any fuse!

[camarogolfguy]

Yep. Try what the manual says to fix it. If that doesn't work, do the dealer. (You know what I mean).

[camarogolfguy]

yep, go see the dealer.
