window moving slow
 

Hi All,what is causing my driver side window to move slow going up,even sometimes stop,then have to assist with hand.it moves normal going down.Thanks in advance.:dunno:

Maybe a window regulator going bad.

Or window motor

When the front window regulators break the rear lift breaks first causing the window to go up slow.

You could either repalce the regulator or do the mrbmwx5 regulator fix :D.

BMWLOVER got it,it was the window regulator.Had it replaced and now the window moves better then ever....thanks guys:D

Your lucky i guess, i changed the regulator and my window still goes up slow! lol.

then it might be the motor for you?

Maybe, the regulator was for sure broken because the window would no longer go up anymore (it was stuck in the down position) but even after i changed it, the speed is still slow. I will try greasing it first maybe.

Had the same issue with driver's door - ordered a new regulator and it was still slow, so I put the old regulator back in and bought a new motor and that fixed the "slowness".

My front passenger window is also slow going up and down.

For those that have changed the regulator or motor, what do the jobs cost?
