I have a 380SEC (126) 1984 year of manufacture :cry: and the car is fitted with seat belt extenders, that dont work..Could anybody give me help on how to troubleshoot.
if so - the extenders themselves are prob ok - its prob the switch / fuse.
do the interior lights come on when the door is opened? if not - then its prob the sitch. if they do, its prob the fuse. in my 140 coupe the fuse is in the boot.
sometimes pulling the fuse and re-setting it re-sets the computer...
