What to do if a car window can only go down but not up?

[VonPiper]

Solutions for a car window that can only go down but not up include: 1. Initialize the window, which is usually caused by a malfunction in the window control system; 2. Remove dirt from the window lift channel by inserting a chopstick wrapped in a wet towel into the guide channel and moving it up and down to clean; 3. Apply lubricant or replace the window seal. Most cases where the car window cannot move up or down are due to mechanical jamming, and applying some lubricant after cleaning the guide rails should resolve the issue. Car window regulators can be structurally categorized into arm-type regulators and flexible-type regulators. Arm-type regulators include single-arm regulators and double-arm regulators, while flexible-type regulators include cable-type regulators, belt-type regulators, and flexible-shaft-type regulators.
