Is the headlight sensor the black thing under the grill?


I washed my car on sunday...and the auto headlight sensor thing has been acting all funky. I cleaned the sensor and make sure there's no water spot on it. Usually when it is day time and i drive under a bridge, my headlights will go on till a couple of seconds after i pass the bridge. But ever since the car wash, my headlights just stays on. But when i switch it to off then back to auto, it'll detect that it is the day time. I have no issue of it changing from daytime to night time, but only from night time to day time.

It actually works fine now, after a couple of days. Weird.

Have this happened to anyone?

 

Headlight sensor is on the dash.. Under the front grill is the outside temp sensor

 

I don't have the car yet, but since you have the Tech package in your sig, you might be referring to the ICC sonar under the grill.

 

Maybe it was something you used on your dashboard??

 

Zigackly right

I always thought it was the laser guided whachamacall it.

Check your windscreen for dirt and the sort (I think the sensor is bottom drivers side)
