W204 C200 Electrical issues
I recently bought a 2007 w204 C200. The car is overall doing well but lately I noticed some issues with it.
1. The door lights don't turn on.
2. The transmission lights turn on for a split second and then turn off.
3. The security system is disabled or it seems to not turn on.
4. The rear door locks do not lock/unlock using the key.
5. Auto lights always stay on during day time; only once or twice in the last month they switched off during day time; they remain on otherwise.
6. Once or twice the right parking lights stayed on after I switched off the ignition and locked the car, eventhough, the lights were at '0'.
The previous owner told me that the front SAM of the car was changed and I am suspecting that this installed one is also faulty or is not the correct part.
I am new with Mercedes and your guidance would help me a lot to troubleshoot the issue.
