When I turn on headlights I have no low beam, but I have high beam. My dash lights go dim when I turn on my on my headlights, when I turn the headlights off the dash lights are normal brightness. Is the problem in the wiring or my light switch?

Hi,

Chances are the switch is bad. However, it could be related to the body control module. Do me a favor. Take a look through these diagnostics and let me know if it is something you feel comfortable doing.
