For some odd reason, I can not index my windows on my new C7. Has anyone figured out how to do this, or did GM just skip this technique on the new cars? The current setup means the doors are very hard to close unless they are slammed which we all hate.

Mine seems to have minimal indexing also, and the wife had a hard time closing the door during our 4400 mile trip home from the Museum.

We didn't have that problem with hers ('14) 15 months prior, so it appears that something may have changed related to the indexing.

don't ever close the door with the windows all the way up or you'll soon be buying new window components and seals. Here's an easy way to index:

pull the NEGATIVE batt cable for 10 min. when you attach it back, it will ask you to index the windows....

I usually have to slam mine twice before it closes right. And there is no place to grab to close it. I usually use the window so I don't scratch the paint. Mine is a 16 as well.

Dracla

Does that work on a 2016? I know it will work on an earlier model.

I use the U shape striker bar on the inside of the door jam to close the door, one finger, never touch the outside of the door.

I do the same. Works well.

Dracla

That may close the door, and it does not leave fingerprints which is a problem. But...can the windows on a 2016 be indexed?

Glen e

The 16 is no diff wiring wise than a 14 (re this situation) and disconnecting a Neg cable should have nothing to do with years. Call your local dealer and ask. It will be the same.

Are you saying that your windows do not lower approximately 1/2" when you open the door?

Dracla

Correct. They do not. And I tried indexing a la 2014 and on my 2016 it did not work.

Streetrod782

Mine index just fine. As a matter of face had them tinted yesterday and the indexing was causing problems. They had to re do it twice. Just very hard to shut!

Dracla

Is yours a 2015 or a 2016?

Indexing is working fine on my 2016 also - they will close easier as they are used more - my driver's door closes easier than my passenger door

Dracla

Well now I'm thinking that if indexing works on a 2016, I guess I have to go and figure out what I'm doing wrong. Thanks.

Glen e

do you mean you did the neg cable disconnect? did you stay disconnected for 10-20 min?

Dracla

It's a new car. I did not do the neg cable disconnect. Maybe if all else fails, I'll try that, but then that would mean that I have to reset everything.

tunaman

Indexing works on mine, but doesn't appear to lower as much as on my previous cars. I'll have to compare the wife's '14 to mine to see if there is a difference.

Glen e

Again trust a few of us that have done this several times ........you lose virtually nothing when you pull the battery cable ....it's because most the settings are stored in NVRAM, now , instead of needing current like past Corvettes. Just do it.

Done here.

Wow, what a timely thread. I just picked up my first Corvette yesterday and had a heck of a time closing the door. It sounded good and felt right but 3 times I had to pull over and come to a complete stop in order to open and slam the door. Annoying that I can't just pop it open and slam it without having to pull over and stop. Those electronic nannies again!
Guess I will disconnect the neg terminal before I go ahead with all my personalizations
