What is the reason for slow and weak window rolling up?
3 Answers
Car window rolling up weakly may be due to the following reasons: Window glass regulator damage: The car window regulator is a door accessory in the door system that realizes the lifting movement of the door glass. It is a special component for adjusting the opening size of the door glass window. Its function is to ensure the smooth lifting of the door window glass and the smooth opening and closing. If it is damaged due to aging or impact, the window glass regulator needs to be replaced. Window stuck by foreign objects: Aging of the glass sealing strip increases the resistance to lifting. If the glass guide rail is stuck with foreign objects or is too dirty, it will also cause the window to fail to roll up. Clean the guide rail and apply lubrication, and replace the car's sealing strip at the same time.
Oh, my old Chevy has the same issue - the windows roll up slowly and weakly. After checking, common causes include dust buildup in the tracks or dried-up lubricant, creating excessive friction when the glass moves; worn-out motor with reduced power output; or dirty switch contacts causing poor connection. You should check if the tracks are too dirty - try vacuuming the gaps and spraying some silicone-based lubricant. If it's a motor problem, replacement could cost a few hundred bucks. Try to prevent kids from playing with the window switches to avoid accelerated wear. It's most troublesome during rainy days or emergencies - better fix it soon to prevent the window getting stuck halfway, which could be a safety hazard.
I've been driving a Honda for over two years, and recently the right window suddenly started rolling up extremely slowly with no power, which really frustrated me. The cause might be simple, like insufficient battery charge leading to low voltage; the switch not working well due to oxidized contact points; or a half-blown fuse. A simple solution is to turn off the car and restart the system to see if there's any improvement. If that doesn't work, check the fuse box and replace the corresponding one. Loose wiring connections can also cause this, so try unplugging and replugging the connectors. Don't ignore it, as driving with the window open on the highway can be dangerous.
