Power Window Problem, Passenger Window Stuck Options

[Helix]

Here is the problem. The passenger's side window gets stuck from times to times, but only when it is fully closed. Sometimes it starts working again without me doing anything. I had some electricians look at it but no one knows what the problem is. All they can do is connect the motor to an external power supply, thus making the window work for a while, before it gets stuck once again(in a day-week-month).
I don't know if it has anything to do with the problem, but before it happened for the first time, i had the chip that automaticly closes the windows when i engage the alarm replaced because it stopped working.
Please help me. I am in this sittuation for some time now...

prolly needs to be regreased..

they have a relay that automatically stops feeding power once it reaches a stop. either fully closed or open.

hence if its not sliding adn getting stuck, there lies your problem

i would take the motor out and paly with the switches. if it works then take the whole window out with tracks anc check for any broken pastic bushings or signs of wear. take pictures before taking things apart so you remember...
