Why is it that my headlights work sometimes and other times they do not??? Is it in the "****" I use to turn them on with?? HELP!

 

Oh yhea, it's a 2005

 

are u under 36k miles??? if so go to the dealer and have them look at it. If u dont have a drb3 inorder to show if the mux signal is getting from the headlight switch to the BCM and then to the front controler trough the ipm then u are guessing and spening lots of money. bcm 500 front controler 250 ipm 300 headlight switch oo i duno 100 so take your best guess with out any test computers.
