What Causes the Car Window to Not Open?
2 Answers
There are several reasons why a car window may not open, including wiring issues, motor failure, lack of lubrication, or obstructions. Below are detailed explanations and solutions: Wiring Fault: A malfunction in the sunroof wiring can prevent the window from opening; replacing the wiring can resolve the issue. Motor Damage: A damaged motor in the car sunroof can cause the problem and requires repair. Lack of Lubrication: Severe lack of lubrication in the sunroof track can cause the sunroof seal to stick to the car body. Obstruction in the Track: If there is an obstruction in the sunroof track, first check if the electric sunroof fuse is blown. If the fuse is intact, inspect whether the electric sunroof switch is functioning properly, and then check if the electric sunroof drive motor is operational.
It's quite annoying when the car window won't open. I've studied this kind of problem several times. There are usually just a few common issues: It could be that the window regulator motor is burnt out or the gears are jammed—if you hear the motor sound when pressing the switch but the glass doesn't move, that's the problem. Another possibility is aging contacts in the window switch, causing no response or intermittent functionality. Then there's poor wiring contact, where wires at the door hinge area get repeatedly bent and may fray or short-circuit. Also, if the child lock is accidentally activated, the rear windows won't respond no matter how much you press the switch—check the small switch on the side of the door. Oh, and if the window suddenly won't open on a rainy day, it's likely due to the aging and swelling of the rubber seal in the glass guide channel, temporarily jamming the glass. Spraying some dashboard wax can help in this case. If the window stops working, don't keep pressing the switch forcefully—it could blow a fuse. The safest bet is to have it checked at a repair shop.
