Obviously not the bulb, as it's the same one handling both functions. This is for the driver's side BTW. The running light doesn't light up when pulling the headlight knob on the dash to either the first or second detent. Anyone have an idea what the problem might be?

Some bulbs have 2 filaments. Maybe one is burned out....
If not that then you might remove the bulb and put a VOM on the contacts in the bulb socket to see if power is there (in the right place) for both functions. That is the extent of my troubleshooting.... (IMG:style_emoticons/default/mellow.gif) |

I switched the bulbs between sides and the problem stayed on the same side, so I think the bulb is OK. Good idea on using a meter to test the functions, I'll try that. |

probably the contactor under the bulb if the bulb is know to be good. . or the wire lead is loose off the spade under the rubber cover.
Look inside socket for corrosion, and make sure it is high enough to touch bulb base. . The brass tab can be bent upwards a tad bit. |

The spade is riveted to the light assembly but the rivet may have failed allowing the spade to come loose.
