Drivers window

[erisol]

Hi, my driverwindow dont work, i hear the switch clik as it shuld and this sound disepear when i remove the socet under the switchcontrol on the door.
All three other doors work fine, this may be the switch or the el motor?
What is a windowregulator, is this an electric component or mecanic divice?
I see under how tos, and that looked like a metalframe whith wires, wil the el motor run if its the regulator who i understand is a comon problem?
All fuses are ok.
