Check the dimmer switch adjustment at the base of the steering column. If it gets out of adjustment you will lose either low or high beam lights. If you have high beams the light switch on the console is working. If you can't get voltage out of the low beam side of the dimmer switch, it can be easily replaced. I recall it is off a Ford F-150 from the late 1980's. I got one at the Ford dealer in Yuma when mine went out several years ago during a trip from Texas to California.
