Need Window Advise on C6
On my C6 Vert, the window is supposed to go down a little when you open and close the door. All of the sudden, my driver door isn't doing that. How do I fix that?
This is known as indexing windows. Needs to be done if you loose battery power!

BTW, you have to have the door closed to re-index the window properly.
It will not work with the door open.
When you push the door handle, the window should index down to clear the roof weather stripping seal, then upon closure, the window should go up and seal against the rubber.
If the window is not aligned properly, straight across to top, or not pulled in enough from the top portion, then it will not close or seal properly.
There are 4 adjustment bolts on the window regulator to pull/push out window, and the glass holder brackets can also be loosened and adjusted so that the glass sits evenly on the roof weather stripping seal. Once the glass holder brackets are loosened, the glass can be shifted East to West, or North to south.
If the glass is hitting the front portion of the top seal, then loosen the glass holder bracket adjustments bolts and slide the window back so it does not hit the front trim. If the window seems too high, then loosen the bracket bolts, and lower the glass down a bit, then re-tighten, and check to see if it fixed the issue.
If re-indexing didn't work, then you will have to remove the interior door panel, and adjust the window as needed.
