first time to help an old lady to solve a myvi door window stuck problem.
passenger side door window  failed to raise up even press the window control buttons on both driver side and front passenger side.
it could be lower down by pressing any one of the driver window control button or the passenger side window control button.

unscrewed and opened up the arm rest cover at passenger side, cable wiring seems alright(though no multimeter around to measure the voltage change).

does any one here has this experience and how to solve it?

is it due to mechanical issue or electrical? how to distinguish and troubleshoot?

thank you for any recommendation.
