1986 Chevrolet Corvette Power Windows

I would like some more detailed explanation on what stops the window motor at full up and full down positions. Are there limit switches? If so, where are they located? If a thermal switch acts as a limit switch and shuts down the power, why do I not hear or feel the wingdow try to work when I touch the button again? I am working on getting the windows to match up to newly replaced weatherstripping. I suspect a limit switch or relay issue that is intermittent is adding to my troubleshooting woes. It is tough to diagnose when I don't have an electrical diagram that shows the limit switches, if applicable.
