I have problem; bmw e46 2000 model rear electric windows fuse-ok

I had the same problem. when you press the close/open button can you hear clicking noise under the pannel? if yes, you will hawe to chenge the relay. only place to get it is from this site: http://www.bmwgm5.com/GM5_FW_Relays.htm

It is most likely the window switch, motor, or most likely the lifter assemby. The lifters are a known issue with the windows. If you have a meter you can check the power delivery to the motor contacts (rear door panel removal required). If you don't have a meter then you can try to listen for the motor to engage when you press the button. To check the button, you again need a meter to check continuity. Remove the centre concole, disconnect wiring harness from button, and depress. With a meter attached you can tell if it's making contact. Often, because of the locatin of the bottoms, they can get dirty or damaged and require replacement. Once you've isolated the faulty component, a good source for the replacement parts is Pelican. http://www.pelicanparts.com/bmw/catalog/shopcart/BE46/POR_BE46_ELswch_pg5.htm
