Hi all! I have a 2000 Merc Vito with a nasty Meta alarm fitted. My prob is when locking the van with both windows down the drivers side closes fully but the passenger side only gooes 3/4 way up. The motors are fine in both windows as both close at the same speed if both switches are held. Thanks in advance for any help. Simon.

 

if theres a build up of dirt or tree sap on my windows i have the same problem failing that it may need a new window closure module

 

Got that sorted. It was a build up of dirt, cleaned it and hey presto it works fine!! Cheers mate.
