    My head lamps are both not working, so I went out and bought new ones and there still dead. The two lamps in the middle of my grill are both working after I replaced the bulbs. Where should I go from here??? Need help guys/gals..................need to pass inspection!!!

    Dimmer Switch? Switch from low to high beam and see if they light up. If so its the dimmer. Also check the headlight switch. From there wiring YUCK! Good luck

    Which one is the dimmer switch?? I know this sounds stupid, but I barely took my rig out of storage a couple of months ago.

    Upon investigation I found the "dimmer" switch on the floor board!!!!!! I feel so stupid!!! I clicked it and my headlights came on!! They only work in one setting, though. At least I have head lamps! What now??? Do I have to replace the dimmer switch????

    Get a test light or voltmeter and start checking for voltage at the on/off switch. Keep going towards the lights until you lose voltage. This will show you where the broken wire/switch/relay/etc. Good luck.

    If it ain't broke, fix it 'til it is.[​IMG]

    Replace the dimmer switch. 2 bolts. Just lift up the carpet, unplug the wiring and install the new one. Cost about $6.00 for me. I had same thing happen and since I hate wiring i took a chance and replace mine. Bingo.
