Gonna need to take my C6 in to have this repaired but thought I would first ask here for any possible advice or input. I have a 2012 C6 convertible and I noticed this morning that the rider side window did NOT do the small downward move when I went to open that door. I noticed that in time to not harm the window by getting it stuck under the convertible top. Instead I went around and rolled the window down a ways from the driver's side control. And it's NOT just the window indexing. The window will go up and down but at the bottom in stops with a small amount of glass still showing. I would say it needs to go down another inch to be like the driver's side. I did go ahead and do the indexing procedure just in case but that did nothing to make anything better.

The convertible top still works and when you activate the top it does roll both windows down as one would expect but the rider's side window just stops too high, at the wrong place.

I need to take it in soon for an oil change and now for this but can anyone suggest what this might be so I'm as informed as I can be when I go in??? An adjustment, likely?? Something more?? Any thoughts??? thanks...

 

I hate to say it but I think I'd be trying to index them again... Seems mighty fishy.

If it is a window regulator, they're a pretty easy DIY repair. Get the part at the auto parts store for $40 or so and grab some tools.

 

I hate to shed bad news but I just paid $292 from Amazon. delco part from parts store is $446 and doorman is $592

 

I imagine that you need to index your windows again.

 

Wouldn't hurt to try it.With the engine running and the window down, 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. Don't forget the other window. This will need to be done to both windows every time the car battery is disconnected, then reconnected.

 

Hmmm... To those of you above who said that I might need to index the windows again, you were mostly right.

I read the manual and did the procedure which is precisely what Vette DD said above. With the windows down, roll them up, hold for three seconds after reaching the top, release, and then hold for another three. Did that... Did no good. But, read on.

I do know that once upon a time I needed to re-index and I'm sure I would have simply looked up the procedure in my manual which is just what Vette DD described. And in that time a couple years ago, it worked... Hmmm..

So since it didn't work this time and since I was going in for an oil change anyway, I asked my local dealer that does tons of Corvette features to give it a look. They came out and told me that re-indexing did the trick but they said (which is different from the manual) to,

"lower the windows all the way and hold for three seconds at the bottom, then raise to the top and hold for another three seconds".

Hmmmm... Certainly not what the manual says... But that's what they said they did and the window works just fine again. Cost me $25 for a tad bit of labor.

I have to say that it sort of seems like holding for three at each of the two extremes sounds intuitively reasonable but again, this rider's side window was not even coming down all the way so you would NOT want the window to re-define that as "bottom"...

So color me confused.

But yes, it was some form of needed re-indexing. Maybe had I just persisted and tried "this and that", maybe I would have saved $25. But it could have also been a bad regulator or worse so I'm happy to have asked them to fix it, which they did.

Anyone care to comment on "all the way down for 3 seconds, then all the way up for 3 seconds" which the dealer said fixed my issue"???

Anyway, working again... Thanks for all the help.

 

 

Doesn't/wouldn't surprise me. These C-6's are full of surprises when it comes to their functionality. If mine isn't throwing some bogus "fob not detected"....or it isn't blowing off the door open chime inconsistently I would think that it was in need of some kind of repair !!.........

 

Never had to re-index my windows on any of the 5 C6s I had. I just got the information for others out of one of the 5 Owmer's Manuals I had in electronic form AND from the dozens of forum members who used the one I posted and it worked according to them.

 

It was the Service Manager who told me it was the down for three and then up for three. He's pretty good but he's NOT the guy who actually fixed it so we might have a bit of the message getting messed up as it travelled from one person to another.

But I certainly did the up all the way, hold for three, release and then hold up for another three, more than once and it certainly didn't work this time for me.... So a tad bit of a mystery but bottom line is it was in need of some level of re-indexing and that is all that it was.

And windyC6, yep, count me in as well for the

" blowing off the door open chime inconsistently"...

I bought my 2012 new and it's done that chime deal now and then since it was a baby. I don't even pay attention to it anymore. I just smile, close the door and drive away...

 

 

I certainly did both drive and passenger and the accessory was on but I can't say with complete certainty (memory) that both doors were completely closed. Just can't recall for sure.

 

That's the way i have always did the indexing on my 2008...I think the salesman told me that was the correct way....BTW: No need to start the engine either put in acc mode will do it.

 

Well, color me unsurprised that it is not documented.
Where did you get the manuals in electronic form? I'd love to have that for my 13.

You did the procedure a couple of times so I find it super hard to imagine that you didn't have the door closed properly. It's not that common at any time much less when your specifically doing a procedure that not closing the door right would influence. It was closed proper and you would have noticed if it wasn't.

 

I wonder if they don't use back EMF or maybe they have a tach wire on the drive motor for positional feedback. And maybe in some cases both the top and bottom settings need relearned and that's why most people here have not heard of the down indexing, and have only required the up indexing.

I can Envision a situation where One Direction is enough most of the time.

 

Google around, they are out there, for free. One huge advantage over a hard copy is it's much easier to do a "Search" electronically than thumb through a 400+ page tome.

Stupid of me for not thinking of GM for that. But somehow I figured anything you get from them would have to be at cost.

Thanks.
