Hi, I have a 1999 300M and the window fell off its track, could anyone help me fix the problem. I haven't opened the door panel before.

 

well can u move the glass??? if u can this is the part to repair the borken lift glass bracket . Attached tsb
if the lift plates are not broken then u will need to replace te regulator and motor assembly.

 

Actually I can move the glass. How much would a lift bracket cost?

 

list price is $8.60 the new part number is 04878907AC now read the instructions on how to replace the lift kit u might not want to get into that need a heat gun, 3m glue and some other tools read the tsb if u want to know all the details
