After having the battery disconnected, my windows won't index. Couldn't find info in owners manual.

 

What do you mean, "they won't index?"

 

With the top up and the windows shut/closed they should drop down a little to allow the glass to not hang up when you open the door.

 

That's in a C6 not in a C5.
If yours is a C6, you're in the wrong section.
BTW to index the windows in a C6, you sit in the car, close the doors , turn ignition on, and roll the window up and keep holding the up button for 5 seconds then let go. It will learn.

 

I bought this C-5 (1998) Convertible last year and we have not had the top up, but I put the top up this past Sunday due to a quick shower and noticed that the windows want to hang up when they are at the fully closed position and I want to open the doors. I know that the C-6 has an indexing system, but I thought the C-5 convert would have one just by the way the window(s) hung up. I will take a look to see if maybe the windows are in need of a up limit adjustment if it is for sure that there is no indexing system on the C-5 Convert. Thanks to any and all who are helping.

 

I tried 3 times to get this thread to open but to no avail. Anyone have a suggestion?

 

I have found the hard way that that there really is no good seal on the Vert.
Your glass could be adjusted to just miss the top and make a decent seal with the vert weatherstripping.
Trust me, I have spent a few hours on my passenger side trying to get the top not to leak, and got it to where the glass passes the top by merely millimeters.
So far I don't get any water in the car when it downpours, but I am not trusting a touchless car wash as it shoots water from all angles.
Yes, water leaks are a trademark of our beloved C5. I've owned about 4 or 5 of them , and most leak in one place or another.

New weatherstripping is discontinued by GM and I am not sure that aftermarket is that much better than what I have in my car.
Have fun adjusting.
If you are not mechanically inclined to do work on the window, I suggest taking the car to an upholstery shop to take care of the problem for you.
Good luck!!

 

I'm not sure which adjustment raises the corner of top to miss the glass. I looked at pictures that were posted back in 2001 and it shows more than one adjustment point. Maybe someone can clear this up for me. Thanks for any responses, Jim

 

This is a very nice mod you might want to consider.

I did not touch the top itself. Not yet anyway. All my adjustments were done to the glass itself.
Moving it forward and backward, and up and down to line up with the weatherstrips. there is also a tilt adjustment for the glass to make a stronger seal, but you don't want to over tilt it.

 

If you take the door panel off, there are two rubber covers towards the top of the door. If you pop them out, there are two 14 MM bolts that allow you to move the glass forward away from the top and re-tighten. I would only do it slightly just enough to clear the top, otherwise the back of the window will leak.
There are also two Torx screws,one to the front and one to the back of the glass adjustment holes with the covers , those adjust how far the window will travel up.

 

So you are saying adjust the glass and not the top. Thanks for this.

 

At least that's what I did. There was not much for the top to be adjusted other than the latch itself, but mine feels pretty tight.

 

I have tried the 13mm adjustment screw to help my passenger side window clear the upper corner of the convertible top but it didn't work. My next thought is to slightly loosen the 3 mounting bolts that hold the top frame to the car and slide the assembly back just enough to gain clearance. Anyone have any experience with this adjustment technique? My driver's side just ever so slightly clears and seals nicely against weatherstriping. Hoping to achieve the same fitment on the passenger side, probably need about a quarter inch movement to clear top.

 

After I installed a new regulator on the passenger side of my 03 vert I had hell getting the window to seal.
I even took it to the local Chevy dealer's body shop for them to fix it.
I was told it was as tilted and adjusted as good as it could get.
I finally fixed it myself.
I went to Harbor Freight and bought one 4" suction cup thing. I got home and took off the door panel. I loosened the two nuts holding the glass in a little and closed the door. I put the suction cup on the outside of the glass and moved the dang glass to where it needed to be.
I opened the door and tightened the nuts and put the door panel back on!
No more leaks and wind noise for me. It's been that way for several months now.
And best of all my wife quit griping about it!!!

 

I'm thinking that's what he meant in his "I tried 3 times to get this thread to open but to no avail. Anyone have a suggestion?" note in post #7.
The post 6 link worked fine for me, but I'm on Chrome, which may matter.

 

Help! I have a 1999 C5 Convertible. It is stock, no mods, unless you count a drop in K&N air filter and new wheels. I purchased the vehicle from a person who had it in storage and drove it sparingly. I've had it for three years now. I have had a few things done such as hoses, AC compressor, harmonic balancer, and fluid changes. The car runs absolutely fantastic! The issue I have right now is the driver side window. About a month ago I reconnected the stock rear Bose speakers and changed the footwell and trunk lights to LED. Actually, one of the trunk lights (passenger side) would not come out so I left it in. I was interrupted by a phone call and left the garage and went inside to talk. Well, it was a long phone call and I fell asleep. The doors and lights were left on and the car battery (Duralast brand) died. AAA came out and charged it. Nothing was disconnected. Everything worked fine afterwards, no DIC warnings popped up. Actually, none have since.

Issue: The buttons on the switch for the passenger side window, door locks, and mirrors all function as normal. I do not have the memory seats. The driver side window button clicks when pressed in the up or down position. The up position clicks immediately when pressed; the down position has a small delay in its click when pressed.

Below is what I have done to try and fix the issue:

1. Bought and installed a new window regulator and motor.
2. Purchased and installed a used control switch and installed. (ebay)
3. Purchased and installed a used relay module box. (ebay)
4. Pulled and re-installed the associated fuse in the floor fuse box.
-The window actually worked for about a week and a half and did stopped working in the up position same as the original issue.
5. Tried the fuse pull again, didn't work. Input a new fuse, didn't work, had Autozone test the fuses, all are good.
5. Applied some contact cleaner to the switch connector and wire harness that it connects to, waiting for it to dry/drain as I type this post.

Sorry so long, but I wanted to make sure I captured all that has been done so far.

Thanks

Randy

 

Guess you never looked where I said mine was pretty tight as it was.so no more adjustments could be done to my top . RIF

 

That is basically what I did without the suction cups. If you loosen up the glass slightly, you should be able to move it around and it stays where you put it for fine tuning and final tightening down. It worked for me too.
