Do I need to code this part or something?
I own a E320 96 and
I was having an issue with my driver’s side window that was with no power to lower it.
I bought this used part (electrical module # 2108203926) on e-bay and after installing it my drivers side window works just fine, but now I’ve a problem with the other 03 windows, trunk switch, turn signal & wiper.
What would be the problem any suggestion?
