Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hi,I can help you with this.Before doing anything else, please go to the drivers door and depress the window lock button. This is the square button to the side of the power lock switch. When this button is pressed it shuts down manual operation of the passenger side windows (front and rear), and they will only work with the top automatic operation to go down.
If there is no change in the operation regardless of position of the window lock button, then it is possible that the switch may be failing, but we could try a recalibration first just to be sure ("reset"). It is more likely the window lock button got bumped though... they are very easy to accidentally hit.
