November 26, 2008Yes there is a relay for low beams, high beams and fog if you have them. I just can''t remember if is on the side of the dash *or* int the engine compartment...JohnB
November 27, 2008i checked under the dash, there were a couple, but not for the headlights, and same for under the hood in the electical center ...nothing for headlights??????
November 27, 2008do the rest of the functions work on the dimmer switch on the column, may have had the switch go out for your headlights to go bright
November 27, 2008all the functions work and the switch is brand new on the column...i also had other another problem, and a new directional switch solved that...but i did have the problem before i changed the directional switch....i did switch out the headlight switch, but nothing changed...b
