how much to repair window regulator on 328 xi rear passenger window. on 2007 BMW 328xi

window went down. Loud thud occurred. No movement back up

Can't give you a price but i can give you some advice! Take it to an auto glass shop for the repair, they can fix it for less than anybody. If you can hear the window motor running when trying to raise that window, most likely the glass just needs to be 'glued' back into the bottom track, (most likely)!
Thanks for the tip
Least i could do for a fellow Virginian!
