What Causes the Right Rear Window Glass to Fail to Roll Up or Down?
1 Answers
The reasons why the right rear window glass cannot roll up or down include damage to the window lift motor, poor contact in the electrical control wiring harness, motor overheating protection, excessive resistance in the glass guide channel, or large gaps in the door glass seal. Window lift motor damage or poor contact in the electrical control wiring harness: If there is a burnt smell or abnormal noise inside the door panel when holding down the window button for a long time, it is likely that the window lift motor components are damaged. In this case, the window lift motor needs to be replaced. Motor overheating protection: To protect the power supply circuit, most window lift motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to fail to roll up or down. Excessive resistance in the glass guide channel: During use, dust can accumulate in the glass guide channel, increasing resistance. Over time, this may make it difficult for the glass to roll up. Large gaps in the door glass seal: Rainwater can easily enter the door interior, causing premature wear and breakage of the window regulator cable, leading to failure to roll up properly. It is recommended to check the window regulator cable.
