hi guys,i have a 2001 s430.the windows,door locks,power mirrors,power folding mirrors,seats,light up module that surrounds the seat buttons that glow in the dark dont work either.is there a relay,or module or something that has to be replaced?i had one last year that had the same problem but i sold it before i got it corrected.my foreign car tech said it was a part called the luxury convenience group module located by the passengerside kick plate.but i spoke to a mercedes- benz parts guy to price it and was told that that part only went up to the 1999 s-class.when the 2000 w220 sclass came out and body style changed,they no longer used that module.it has to be something on one circuit to cause failure to all those accessories at one time.please,somebody anybody tell what to do.a knowledgeable layman or a tech.i need help badly.thanks!!!
