my car developed 2 strange gremlins in the past 3 weeks:
1) my headlights always think its night, to they stay on
2) the wipers stay "on" when in the auto position.

I'm wondering if they're somehow related.

How can i check if the sensors are going bad? would there be codes thrown if there's no CEL? im away from my car for the week, so I cant even try to check codes until the weekend.

 

I would suspect the wiper stalk but the wipers and headlights are on different stalks I think??

are the light and wiper sensors close to each other? or linked together in some way?

 

No

Did you have anything done with the windshield? Sounds like the sensors mounted to the windshield next to the rear view mirror are f'd up.
