replace the Low beams.


Probably your headlamps, but make sure your dimmer switch is functioning properly, just because it is new doesn't mean it will work. If the switch checks out might check the low beam power at the headlight connectors.

Trace the electrical connection to the switch back to the hornace. Unplug it. It should contain nine plugs-ins. Position the hornace is such a position as a plug is protruding the farest to the right. The end plug (on the right) in the second row should be the electrical feed for the low beams. Make sure you have voltage there. If not, begin checking backward until you find voltage. The problem will be comewhere inbetween. Check your new switch. Place it ou low-beam and check the proper wire for output. If present, begin checking forward until you locate the break or connect where current stops.
