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.

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.

clean and lube the mechanism..

I know its a pain... but pull it out and clean it up really good.. make sure you lube everything

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.

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.

The tint shouldn't really keep the glass from moving up/down....it might slow it down, but shouldn't stop it completely. Kinda sounds like the tracks are out of whack, or one or more of the stops are misadjusted. You'll prolly see the problem once you get the panels off.

sorry for the misunderstanding, i mentioned the tint because if i get pulled over the officer may have an issue with the tint if i cant roll the window down.

ok so I replaced my driver switch for my power windows the window moves about a half and inch up and down. it will not move any further. its acting like the window regulator is frozen up. the gears look brand new. their is nothing catching.

Does your car have power mirrors and do they work?  At one time, my drivers window would only go down a bit and then stuck.  At some time in the car's past it had been repainted and the mirrors removed.  They Bubbaed the job by simply cutting the mirror wires and butt splicing them back together, and over time, the wires came loose and bound up the window in the tracks.  As the other guys said, you'll just have to pull the panel and get in there.  And lube it all while you are.

The original regulators were regular steel and rusted like crazy. Mine were really scewed up when we replaced them. The good part is the replacement ones are stainless steel and bras and will last a LOOOOONG time! Your's could be really froze up.

  That's a new one!! I would have never thought of something like that....and I've seen all kinds of Bubba-isms!
Thanks for posting that.
Definitely something binding up inside the door....no way to figure it out without exploratory surgery....

well after taking removing the door panel, inspecting stops, rails, rollers, window rattle tightness, i took the power window motor off- its not original- off of Right side of some other chevy.
