Thanks HPF after replacing the fuse 9 again mine lasted a few days but now is doing the same thing. I guess i wll have to tear into the trunk lining and get a part number then try to find it on ebay like one of the other guys instad of eating the full price for a new one. I sure wish there was a place to order parts at a reasonable price. The other thing thats bothersome in reading all those sessions on clsoure assist is that they seem to move back and forth on the location of this pump in the trunk, and these blak snaps that you have to take off the lining once you pry them off some of them break as they are plastic so we will have to order new platsic snaps to put the lining back in place. Thrid on this s320 the pump isnt on the drivers side cause i got that lining out it must be against the back seat, either way 500.00 for the part hurts any and all suggestions welcome thanks
