i had the same problem you need to get your door regulator fixed
Neither, probably be the switch.
what it is called a part of the window that makes window glass of Volkswagen new beetle goes up and down?
there is something wrong with your switch in the door you may have to change it
window regulator
Yes
Try a new switch or just clean the contacts on it
you can take the panel off the door and find the wires going to the power window motor. Take a car battery or charger and hook it up to the wires at the motor. if the window goes up or down then it is probably the switch. If it does nothing reverse the hookup. If it still does nothing it may be your motor. Hooking it up one way will move the window up and reversing it , it will go down.
Depends on wats wrong with it if it doesnt go down or up it may be the window motor or the window regulator. If it goes down but its hard for it to go up you should check if the rubber corridor is crooked or it just needs sum lubricant like 3m silicone paste
Binding window trim. Can you help it up. Silicone spray the window tracks. test the window switch
you need a window switch bank most likely. Can you get it to go up with the button on the door but not from the front seat? If so, you need to pick up a window switch bank. Common Issue.
its jammed you have to take off the whole door panel and window motor to get it back up then it will work fine again.
Anyone have prob w/ sentra power window? Won't go up or down. IF YOUR WINDOW IS NOT MOVING AT ALL(UP OR DOWN) IT IS YOUR MOTOR BUT IF IT IS MOVING EITHER UP OR DOWN, MEANING IT WILL MOVE ONE DIRECTION BUT NOT ANOTHER THEN IT'S YOUR SWITCH
