Repairs: Changing of head lights
Question: My head lights are out and they come on when they want , now my lights have gone out
and i cant drive at night.
Answer: Assuming you have either replaced or have good headlamp bulbs, there has
to be an electrical issue affecting the headlamp operation. There is an ambient light
sensor on the dashboard that detects when it is dark and automatically turns on the
lights for you. If the headlamps are coming on by themselves at all different times, day
or night, that sensor could be bad. Also, you could have either the headlamp switch or
Driver Integration Module (DIM) with an intermittent electrical problem that is making
the lights act up. There is also a relay in the underhood fuse block for both the low
beams and high beams that could be failing. If the bulbs are known good, an no
obvious thing is causing your problem, you would need to get a schematic of the
headlamp wiring and start checking wires for power/ground/opens/shorts.
