I just recently replaced the driver's side window track. One of the issues I am having is that when you roll the window down, it goes real slow and same with it going up. it appears that it's dragging on something that is causing it to go slow up or down. Now when I had the door apart, it didn't appear to be anyway of adjusting the angle...any idea why this is happening? The Passenger side seems to go up and down fine.

I have the same problem on my 99. Take the window motor out and remove the cover and grease the gears. It helps but still not great.

I've done all that...greased the worm gear and gears with lithium grease. really didn't help. I think it has to do with the angle of the gears/ window. The Diablo track design is horrible!

Check the Volt. going to the motor I think it's low.

I was also thinking it was the voltage also...

Agree... because mine hauls a$$ going up and down.... should not be slow at all..

hopefully this is not another wire that needs to directly connected to the battery.

There is another way apply baby powder on the rubber on the bottom of the window, Im serious some times it works and it doesn’t cost you a thing (it worked with mine!!)

Correct me if I am wrong but wouldn’t that be washed away when you wash the car or blown by wind when you drive the car
