How to Fix Car Door Window That Won't Roll Up or Down?

[DeBrantley]

Here are the methods to fix a car door window that won't roll up or down: 1. First, address issues such as window misalignment, difficulty in rolling, or automatic lowering when trying to raise. These problems are mostly caused by excessive dirt and debris in the window guide channel, which increases resistance. 2. Clean the dirt from the window guide channel. The tools needed include: a chopstick, a small towel, and a basin of water. Wet the towel, wring it out, and wrap it around one end of the chopstick to create a cleaning tool. When the towel gets dirty, remove it, wash it, and rewrap it to continue using. 3. Insert the towel-wrapped chopstick into the window guide channel. Adjust the number of towel layers wrapped around the chopstick based on the channel's width to ensure the thickness is appropriate. Move the tool up and down inside the channel to clean, and periodically remove the towel to wash off the accumulated dirt until no more dirt comes off.
