Okay, this is really strage. What happens is that the left headlight bulb will be okay when I switch to high beam light, but the low beam light is not coming on. The right headlight is fine though. The left headlight bulb is good. I took both headlights out and put the right headlight into the left headlight socket and it does the same as with the left light. I tested for volts, and both headlight contacts read exactly the same: 14 V when brights are on. 5 V when brights are off. 12 V on the low beams. The low beam on the right works fine, but the left low beam does not come on, although it registers 6 V with the digital amp meter. Why isn't my left headlight low beam coming on? I know for a fact that both bulbs are good and the amp meter is reading the same on both headlights.
