I have a 3 camera / sensor setup on my 2012 cls 63 amg front windshield.
Current issues:
Headlights turn on late at dusk
Interior lights turn on when almost completely night time
Auto high beams do not turn on
Auto tint super sensitive (tint stays on during the day but off at night).
Took it to several shops and conclusion was that the heating element on the windshield around the sensors is damaged and requires a new windshield.
I did buy a new Rain / Light sensor from dealer and calibration specialist said that this was not the problem, windshield was issue.
Does this sound right?
These are only 2 or less cameras - Rain sensor slot is optical but way less fancy.
Optical cameras do use a dedicated windshield heater trace BUT the culprit is the camera module itself.... very highly unlikely NOT the windshield trace.
The cameras circuits are built to fail EXACTLY the way you are dealing with oxidized connections that can not reliably drive high electric current loads.
Use a scanner... likely need new camera or get it repaired at a fraction of the cost through an Internet vendor: Google's your friend.
