Automatic Headlights Inoperative after new sensor install
Hello all. My 2015 C300 4matic, ever since I bought it the intermittent wipers have not worked. So I bought a new light/rain sensor. Once I installed I get the Auto headlights inoperative warning on the dash, but the intermittent wipers work. So I replaced my old sensor and the lights work but not the wipers obviously. So the company I bought the sensor from sent me a new one after confirming the part was correct (which I have the old sensor and new one they sent so they didn't just send me the old one back). So last night I installed the new one same thing Auto lights don't work, but rain sensor does. Is there something that needs to be reset for Auto Headlights? Any thoughts? Thank you for your guidance in advance.
