Some Acura MDX owners report experiencing issues with window operation that necessitate the driver's side door to be fully open. These problems include the passenger side power windows functioning only when the driver's door is opened more than a quarter of the way, with no response from the controls when the door is closed. Additionally, wiggling the door harness may cause the windows to freeze or stop working altogether. Some owners find that resetting the power window control unit by raising the driver's window fully and holding the switch in the auto UP position for two seconds can help resolve the issue. Other potential causes include a faulty harness between the driver's door and the car body, which is a common failure point as the vehicle ages, and a blown 30 amp fuse near the driver that controls the driver's window and rear left window. Lastly, issues may arise from a door sub harness that can suffer from wire fatigue and failure over time, suggesting that checking this harness for damage could be beneficial in troubleshooting the problem.
