Using the available manuals, I have one window almost dialed in, goes to the right height and is level (correct angle). The only problem is when I lower it and then raise it. It will raise on the right angle and level but tracks/slides forward. So much so it will bind on the front weatherstripping and stop. I’ve used the various a, b, c, d, adjustment points in the manual, but feel I may be missing a stop/bumper somewhere. Any ideas?
The rear of the glass needs to be adjusted 'down' so that the top of the front edge does not contact the forward weatherstrip FIRST. There may also be some issue with "wear/slop" in the tracking system which allows the window too much 'free' movement.
I respectfully question that. Let me add:
If I put the window 1/2 way down, and hold the glass on front and back, I can slide the glass easily 2-3” front to back and back to front, The result is it rises anywhere within that range, especially forward with the door closed it will catch. If I raise it with the door open it will bind and stop as well. I then shift the class rearward and it will the rise once again. There has to be an adjustment to limit this front to rear sliding. Once fully up, there is NO movement.
Are there stops I may be missing on the horizontal track that limit this front to rear random movement?
Is there one thing that would allow this? I think the furthest back position is appropriate. The problem arises when it is allowed to move forward on its own. I am guessing there is an adjustment I do not see or a stop that is missing in/on the guides.
Thanks Peterbuilt, This may be what I worked from to get to where I am. I relocated and just parked it for several months the way it is. I have new door panels I want to get installed rather than letting them just sit, so I want to resolve the window issue. Maybe my brain is ready now. It is tough to watch and see what is going on inside the door skins as you know. Again, Thank you.
You can not repair or correct a problem with your window with the door panel in place. It must be removed to do [nearly] all adjustments and/or repairs.
Thanks 7T1vette, Well aware. Here was my statement: “I have new door panels I want to get installed rather than letting them just sit, so I want to resolve the window issue.“. I have other cars and between the relocation and working on others, I am just now getting back to this car’s window,
Something is loose or very worn in the window mechanism. I would suggest you remove everything from the door and inspect it on the bench. I had to replace my drivers side window regulator last winter because the window would not come up in the same place twice, and would settle back down after it was up. I was amazed at how much wear there was after 42 years!
did you ever determine what parts were worn? When you say regulator are you referencing the entire internal assembly?
If you go to any of the Corvette parts suppliers (Willcox is a good choice) and search for 'window regulator' you will see which part I replaced. In my case the bulk of the wear was at the central pin where the two 'scissor' arms pivot.

Will Do. Thank you. Hate to have to tear this out again. Should have caught it earlier. Was hoping there was something in the adjustment I had missed.

Thank you again and Happy Thanksgiving.
I just pulled the regulator out of the car and I noted a great deal of play and wobble on the scissor pivot point. I also noted that the arms are not flat. It seems to me that the primary arm actually could be bent a little but I am unable to ascertain if it is made that way or not?
Did you replace the entire assembly/regulator or were you able to replace only the bushing/pivot? If so, it looks like a challenge as it appears to be a press and would have to be redrilled and replaced with a like item.
Thanks again. One way or the other, I need to get this corrected.
Thanks. Just checked to confirm. Removed regulator and found lots of wobble but no sign of what would allow the window to shift front to back. The front guide is in place and see no movement. Getting ready to reasssemble to confirm operation as I don't see what could be causing this. I would replace the regulator but don't see how a wobble at the pivot point would cause movement so maybe I have it assembled incorrectly if possible? Looking for a blow up diagram now to see if I have this put together correctly.
When putting doors back together the best diagram was from a parts catalog. I don’t remember which one, but it had the outside door skin removed showing all the internals in place. Midamerica Corvette?
Thanks. I just reinstalled the entire assembly and had much better success for whatever reason. At present, the only remaining issue so far is that the glass tilts too far inward. I see from the diagram and procedure what controls the in/out but so far still leans in too much. I did notice that the roller that slides up the forward track seems to have a great deal of play and I did not have to remove that roller in order to re install the regulator. Do you know how much excess play is normal for the forward track roller? Also, still can't understand the purpose of the foremost roller as it seems to do nothing?
