Everytime I turn my truck on the headlights come on regardless if it's sunny or pitch black outside. My DRLs NEVER come on and yes ... the bulbs are new. I can disable the headlights if I push the park brake in a notch or 2 before I start her up. But I don't feel comfortable leaving the park brake engaged while I drive. I am assuming my DRL sensor is inop. Any help will be greatly appreciated. Thanx!
