My 99 Civic drivers door window works like new after having a body shop replace the old dried out run channel in the car door window frame...should have made the fix a long time ago, but thought the problem was just in the regulator (metal tray window sits on.) If your electric window opens & closes really slow...it prob isn't the regulator motor (like I originally thought) A fresh run channel works wonders if its not lining up flush.
Excellent replacement part is OEM it will fix my windows as they take a lot of time to be open and close because the original part is old and gives resistance to the window while moving.
