I have a 2001 Ford Ranger Edge Package 4.0SOHC I am having a problem with the headlights. The parklights, taillights, and signals allw ork fine but the high or low beam will not work I have check the high and low fuses and main fuse and they are all good and of course i have checked the bulbs and they are good. I have found that I am not getting power to the headlight switch in the dash what could cause this. Its about to get the best of me!!
