Checking B+ voltage with a DMM - digital multimeter is ! Free wiring diagrams here http://www.bbbind.com/free_tsb.html . Do you know what a automotive electrical diagram is ?
Enter vehicle info. year , make , model and engine size . Under system click on lighting then under subsystem click headlamps . Click on the search button ,then on the blue link. Circuit breakers hardly ever fail . Probably the switch or dimmer switch or a bad ground .

Electric Testing Techniques You Need to Know
SOURCE: fuse/circuit breaker for cig.lighter/radio/dash lights
The heavy duty or 'circuit breakers' should be in the engine compartment, perhaps in front of the air breather.There are one or may be 2 inside behind the front side kick panels driver and passenger side, or under the steering wheel.
SOURCE: low beam headlights not working on 2004 Pontiac Montana extended
You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.
I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp
SOURCE: headlights wont turn on
The sound system was causing to much of an unpredictable power usage on the headlights and the fuse has blown as a safety precaution.
SOURCE: fog lights do not come on.
REPLACE THE FOG LAMP SWITCH DOWN ON THE STEERING COLM. REMOVE THE PROTEC. PANEL UNDER STEERING COLM. AND GENTLY START TO LOWER THE COLM. WATCH OUT FOR THE SHIFT IND. WIRE- REMOVE IT- LOWER COLM. AND HALF WAH DOWN ON THE TOP SIDE IS THE SWITCH FOR THE FOG LAMP CONTROL IF YOU HAVE ALREADY REPLACED THE ELEC. SWITCH - (PUSH BUTTON OR ROCKER STYLE ).IN THE DASH. IF - - LIGHTS AREON AND THE FOG LAMPS ARE TURNED ON AND THE HEAD LIGHT GO OUT OR WONT CHANGE FROM DIM TO BRIGHT REPLACE HIGH/LOW SWITCH ON COLM. SAME PROCEDURE AS FOG CONTOL SWITCH.
