Help needed with auto headlights on 2016 Tahoe Z71.
When Auto Mode On : headlights stay On always, regardless of amount of sunlight. There is NO green indicator on the dash. DRLs are off (see pics)
When going under a tunnel, DLRs turn On, and the green indicator is On. This tells me the actual sensor is Ok, this was recently swapped for a new one. Could it be the headlight switch?
is this normal for GM? I used to have a BMW with auto headlights and they worked perfectly. What else could be happening?
