My headlights won’t turn on…but will flicker when going from low beam to high beam. Also my interior lights do not turn on when you open the door. Is there a fuse relay or is this controlled by the SAM? Does anyone know where to start to troubleshoot this problem?



Hi, thanks for visiting Youcanic, to diagnose your sam circuit, you need to scan it with a good quality scanner that can read all Mercedes Benz modules, the scanner would read the faults on your SAM. As far as I know, SAM modules are non-serviceable. Here is the step by step guide on troubleshooting and replacement of the Mercedes SAM module.
