Q: Car window won't close

Hi there. If the window went down and will not come back up, then either the window motor has failed or the switch is bad. Most of the time the problem is in the window motor itself. It is much harder for the motor to close the window so that is when it typically fails. A mechanic would typically remove the door panel and test the motor for power when moving the switch. If there is no power, then it is the switch or the wiring, and if there is power then it is the motor. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, inspect for electrical problems and replace any electrical components that are damaged.
