Just picked up a 97 Z28, the windows are moving very slow. I have to replace the driver side trim bezel, to keep the switch in place, as well. Do I need to pull the panels off, grease the gears and maybe clean the wiring, to get them to move a little faster, or could it be another issue? Thanks

 

Window motors are the first thing to go on a 4th gen. Anything you can do to make the window go up and down with less drag is helpful, but won't "fix" a tired motor.

Look at the top of the "How To's" section of my website (link in sig) for window help.

 

thank you shoebox, I appreciate the info

 

The driver side window in my 98 was getting verrrry slow so I ordered a new motor. While awaiting delivery, I took off the door panel and noticed the grease in the short tracks was fairly hard and dry. I scraped it out and replaced it with fresh silicon grease. Now the window was much faster. That was 5 years ago and the replacement window motor I ordered is still in it's box in the garage.
