Default slow power windows

I have power windows on my '74, but they are really slow, and need "help" (read, I have to pull like hell, so I'm scared of pulling them off track) closing all the way.

Luckily, here in Las Vegas, I'll be driving in windows-open mode most of the time. But, I would like working windows.

I've looked at all the sites, and there are lots of motors, gear sets, regulators, harneses, switches, etc. But, where do I start, how do I troubleshoot my slow windows? Asside from taking the door panel off, where do I start? What should I look for? Do I need my mulitmeter, what am I looking for?

Thanks,
David

The above suggestions should be done. Not only will this posible make the speed of the window increase, but it will take the stain off the window regulator. The regulartors wear under normal conditions, however the added pressure to raise a unlubricated track will make them wear much faster.

This may sound scary, but you need to completely disassemble your windows, thouroughly clean the tracks and associated parts, re-lube everything, and put it all back in the door! Whew! It is a lot of work, but fortunately none of it is rocket science, just time consuming. the second one will go much quicker. After a few years, the white grease turns to a semi-solid state that is also very gummy. You won't believe the difference. I too thought I needed new regulators, but after I cleaned and re-lubed, the windows now operate very quickly, so fast in fact that I was scared they were going to fly out of thier tracks!! It will make a night and day difference.

Absolutely correct.
My windows were slow for years. I tried the "easy" method of spray oil and spray grease. It helped a little.

A couple years ago I did what Bruce described and the results were amazing.
I had forgotten how fast the Corvette windows were.
It's not that bad of a job.
I removed the power window motor butt'y and cleaned/greased the tracks without removing them. Cleaned/greased the motor as well.
They have been working great since.

:iagree:

I did mine last year, hardest part was getting inside door handle back on.

Take the time to check the alignment for window fit, and mark the bolt locations before you remove them(the one's holding the channels to the door frame) which will save you time trying to realign them. I then took a cardboard box and cut the sides out and used them as a templet of the door panel and drew the outline of everything I took off and actually put the bolts and screws into the cardboard in place. Had no problem putting it back together. I had defective rubber bumpers on the door lock and handle rods, I found out you could get old valve stem bottoms laying all over the ground at a tire store and replace them(I know, it's Bubba-ed). I used white lithum grease on all the channels after a cleanning with steel wool and degreaser. It really ain't as hard as it semms and if you have a AIM, it is easy to adjust the windows if you have t. You can probly do them both in one weekend, but do one then the other just in case. Good luck

I have found NOTHING cuts old dried grease as well/quickly as gasoline...
so in a 5 gallon bucket....2 gallons of gas...and have at it....wire brush....
