slow power window

i have a 98 chilkoot, it doesn't has auto-up feature, but when i pull the switch up, the window goes up. it takes about 30 seconds to close the window. it doesn't has any problem if window goes down.

does anyone has the solution?

Get a can of silicone spray{lubricant} and spray your window runners{rubbber channels}work your windows up and down {engine running}..This may help.If not you have a weak motor.Do not use WD40 or the likes.This treatment should be done whenever you change oil.As a preventative maintenace to help the life of window/sunroof motors.
