External ambient light sensor location
I ran our ‘20 GLC300 through a car wash yesterday for the 50th time since new. The headlights were set to Auto and turned on inside the car wash as usual. When we emerged, the lights did not turn off, and stayed on for the 30 minutes it took to drive home and shut the car off. Never happened before. Lights behaved normally in subsequent operations.
Does anyone know where the external ambient light sensor is? Something new happened in the carwash.

What's your battery status?

I assume it’s OK; it usually settles down from 14.9 to 13V after 15 minutes of 55+ mph. When demand is higher like seat heaters on, or A/C on max, or more driving to urban stores, it may not fully recover until I get sufficient highway miles. I’m retired, so I cheat (of course) and use a CTEK if it stays at 14.9V longer than a few trips. We don’t go out every day.

Good luck.
