Power windows have been working fine. Yesterday, I was running the windows up and down, left them up. Two hours later, driver's side window in up position, will not come down. Moving switch causes the interior lights to dim each time it is moved, so electric at switch should be fine. This is first time this has happened to this 79. Any suggestions what to look for first?
Thanks !

something is stuck...

the dimming is from a huge current draw because something got stuck.. have you tried wiggling the window a little? try lubing up the mechanism?

I agree.Something is jammed and the motor is trying like heck to work.The motor itself may be in self destuct mode and can cause a large amp draw too.Take a look for something jammed in the window reg.area. |hammer| |cheers|

Chutulu and Collector Shark - Working fine now. I was cycling the windows with the engine off. Breaking in the new weatherstrip with the doors closed. Passenger side working fine. I did fiddle with the window while my other half did the switch. Still no luck. I have had a weak battery, and going to replace it with a new Delco when car is finished. Well, I went out this morning to shift cars and truck around, started the Vette, and the window worked. Looks like it needed some more juice. Would there be any reason the drivers side is drawing more current?
I put new window seals on the door also, so all very tight.
Using NAPA silica-glide on the rubber.
Thanks for the suggestions.

I know their is lots of power window discussions, I am having an issue with my driver window, it goes down about 1/2 in and will go back up from their. 

it seems like something is stuck causing it not to move down further- I know I need to replace the switch on drivers side- not making good connection and since it isnt stock the part doesnt want to stay together after I took it apart and cleaned the connections- and I had both switches out yesterday testing the one I need to replace.
even with the known good switch the window still wont go down further than 1/2 inch. 

I tried the "Slam" technique to see if it was something stuck hoping it would knock it loose. still nothing only moves 1/2 inch. the motor sounds like it is trying to move the window. 

I have not gotten into the door yet, spend hours yesterday removing and re-installing the switches (not enough room to work in their Unhappy )

I plan on checking the ground on the window motor and lubing it (where does one lube the mechanism and what type of lube is best for it?) also plan on inspecting the inside of the door for anything that could cause the window to "hang up"

I have the same problem with my driver window on my 81.  It has a mind of its own and it works when it wants too!!  I have replaced the window switch twice and the problem still exists.  I may be infected with a "corvette bug"!!

Sounds to me like the linkage, tracks, and regulator all need to be lubricated. It's a sucky job to get to all of it, but it needs to be done...hopefully it hasn't already damaged the motor.
Does the window just go down that far and stop, or can you hear clicking noises when it gets to that point?

I took the door panels off my car and it seems my power windows need to be well lubricated as well.  If those who have any tricks I sure would love to read them.  I've done this before in other vehicles, mostly the camaros I've owned and was able to make a couple of tools to help reach those "unreachable" areas.

The window just stops at 1/2 inch down. no noise no clicking sounds just stops. it will roll back up that 1/2 inch with ease.
it almost seems like its catching on something, like I said i have not removed the door panel yet this weekend I will be doing that, the problem with the window not working is the previous owner, or original owner put 2 layers of 5% tint on the windows, I have no idea how old the tint is but if i get pulled over they may have an issue with the tint.
