Hi, im desperately after a dcm for my Merc as the drivers window doesnt work but yet all the rest do. Does any one know where i can find one, ive googled as much as i can and amazoned and ebayed but havent found one.

This is the unit and all i can see wrong is the change over relays (tyco), one of the legs doesnt have continuity to the other according to the relay diagram according to tyco. An impossible solder for me to do so id rather change the unit completely. Any help would be awesome
cheers
