Specialty Power Windows

Things to do when trouble-shooting window regulators. These things apply to ALL regulators, whether they are manual or power.

1. Check to be sure glass moves up and down freely in felt run channels. Check front to rear movement. There should be very little movement front to rear.
If glass seems to be slightly snug try powdered graphite in felt channel. Do not use oil type lubricant in felts because it will collect dust and dirt.
If the glass will still not move up and down freely, check the run channels in door and be sure they are perpendicular to each other.
If run channel is right and graphite powder didn’t do the trick, remove glass and take it to a local glass shop and have them run the edge of the glass over their belt sander a couple of times.
Don’t over do it.

2. Use a light to medium lubricant (not axle or wheel bearing grease) and lubricate ALL pivot points, roller or slide channels, (if channel is rusty remove first). Lubricate rollers, slides, counter balance spring and gear teeth.

3. On power regulators make sure motors are securely mounted.

4. Make sure all bolts holding regulator and mounting are tight.

5. Check operation of regulator slowly the first time and look for any possible interference with the other parts of the door (door pull straps, etc.).
