Headlight problems
 

My Marker lamps are really starting to annoy me. The passenger side one went out, and I got it to come back on, but now when I turn my headlights on, the marker lamps dont come on. They only come on when I turn that blinker on (I.E.-when I turn the left blinker on, the left one turns on and same for the right). Anyone have any clue what the prob. could be. I would rather fix it myself because I dont wanna pay labor for something this simple.
