My passenger side headlight went out, and I received "Lamp Out" warning. I replaced the bulb to no avail. When I check the wiring with a test light, I have no power to the dim side. I have check the fuses and everything else I can think of, any ideas?

 

Try switching the headlamps on-off-on a few times. Mine occasionally do that too, I have hella's in mine. The headlamps are actually turned on by relays in the front control module----a node of the main computer.
