What is the reason why the SWM X7 co-pilot window can go down but not up?
2 Answers
SWM X7 co-pilot window can go down but not up for the following reasons: Low voltage: The rise and fall of the window glass is driven by the window regulator. If the car window operates slowly when the engine is not running, it may be caused by low battery voltage. SWM X7 door deformation: If the door is slightly deformed, the movement of the window may be affected, resulting in stuttering. SWM X7 circuit problem: The window movement is electrically controlled, so window problems may be caused by circuit issues, such as poor switch contact or damage to the window regulator.
I've received many complaints from car owners about the passenger window only going down but not up. Based on years of experience, the most common causes are poor contact in the window regulator switch or a faulty window lift motor itself. The lift motor often gets stuck in one direction, possibly due to worn internal gears preventing upward movement while still allowing downward motion. If the switch button gets water damage or ages, it may fail to transmit the upward signal. Another possibility is a broken control circuit, such as a severed connection wire between the door and main panel. When encountering this issue, I recommend first testing if other window switches work normally to rule out system-wide problems, then checking if the passenger side door connector is loose. A simple cleaning of the switch might provide a temporary fix. However, it's best to visit a repair shop promptly - delaying repairs may lead to motor burnout or additional wiring damage, increasing repair costs. Especially during rainy days, having a window that won't close properly can be dangerous.
