W164 Trunk Light dont switch off

[ralf.mandl]

Hi

My Trunk Light don´t switch off after trunk is closed.

always 12 V on Cable

and also.. without a this 5W Light  in - my Battery drains down in a few days..

I already changed Trunklock - no change

checked cable from fuse Box to licghtconnector - also fine - 

checked SAMS (visual) best conditions - no oxid or other damage

 

Does anyone have a idea what could be the "root" cause of this issu

I think if SAMS don kwno that the trunk is closed.. is allwas puts voltage out and dosn´t get into sleep mode - SAMS drains down battery

 

Thanks for any helf...

SAM Offen, inspizieren sich auf Oxidena. Gießen Sie den Ammoniakalkohol, trocken und alles.
