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"

Marcus

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.

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. Thumbs Up

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. 

anyways
how would I adjust the window properly? what is the best lube to use to lube the tracks? I have not done anything with power windows, on any car or truck in the past except replace switches diving into the door is going to be a new challange for me. I saw some diagrams on Wilcox corvette but it doesnt say how to adjust them in the Tech pics. 

thanks for all the help

Marcus

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.
the window worked great then it sat for a bit and now it wont really budge.

could the window regulator be fried?

it acts like i wants to move but then just stops as if its not getting power. but it will go up and down like i said about an half an inch. I have not made any adjustments to anything just replaced the switch. 
i thought it was the tint but that cant be it. 

I am stuck on this any thoughts???

thanks

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.

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

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.

I manually pushed on the window and pulled it up, no sticking at all

I hooked up the motor ground it out and hit the switch, goes half inch and stops. Motor is Froze up. time for a new one
solved my issue

thanks for the input

update!!!!!!!

Nope not the motor. with the meta 3 bolt plate on it hangs up, without it works fine, upon closer inspection the flat spot on the gear that hooks on to the plate is stripped! 
ha much gear replacement is cheaper than a motor
