68 442 power windows slooooow
Hi All,
Doing some stuf on my 68 442 conveertible and one of the things is the power windows which are slow. I got to help them up but seem to go down ok. I have replace the front window motors with little improvement and tried to see if anything is binding and seems to be ok. Could the regulators be worn out?? Anybody tackle this issue with any success?? Thanks Steve

X2 on the grease. I usually clean the regulators in the parts washer then re-grease. Pull the motor apart inspect clean grease etc...Inspect the rollers replace as needed.
Slow motors can be caused by a prob with the motor, the ground circuit, the switches, the wiring, and a bad window adjustment. If there's too much resistance anywhere it will slow the motor. Check the grounds and the switches for high resistance. Switches could be dirty or burnt.
You could do a voltage drop test. That will help pin point the problem.
Adjustment plays a part here too. If they are rubbing too hard on one of the window guides that wont help.
Thats why I like to remove the entire assembly(after good notes and pictures). Clean test and re-grease. Install and adjust.

And hopefully new doesnt mean off shore garbage. An AMP probe on the power wire or an inline gauge will spot over load. Another good tool to have. Let us all know what you find. Close the loop on the thread for future searchers. TX!

I have tried to move them manually with the motor out and they seem to move ok. Unfortunately these are not real gm motors. They were given to me as a gift and look well built. I will have to keep a it and see if I can find the problem. Steve
