[McCarmen]

The causes of intermittent failure in power window operation are: 1. Deformation or damage to the glass channel; 2. Loose screws fixing the window regulator; 3. Damage to the window regulator; 4. Misalignment in the installation position of the guide rail. Reasons for difficult window operation include: 1. Damage to the window lift motor or poor contact in the electrical control harness; 2. Motor overheating protection; 3. Excessive resistance in the glass guide channel; 4. Loss of computer data. Solutions for difficult window operation are: 1. Turn on the ignition switch, hold the switch to raise the window, continue holding for more than three seconds after the window reaches the top, release the switch and immediately press it down to lower the window to the bottom for more than three seconds, then repeat the raising action once to complete the initialization procedure; 2. Insert chopsticks wrapped in a damp towel into the glass guide channel, move them up and down forcefully to clean the channel, and continuously remove and clean the towel to remove dirt until no more dirt comes out.
