help..with warning sigals...driver side door

i have a 2001 golf TDI and the interior lights wont work when my driver door is opened, also the warning signal wont sound when i leave the lights on or when i leave the keys in the ignition.....i was thinking it is a fuse, but the lights work when all the other doors are opened, or maybe the switch which "tells" when my driver side door is open.................can anyone help???



Thanks in advance.....

There is a switch that is part of the door latch mechanism, unfortunately it isn't available seperately.
