1999 Dodge Caravan tricky low beam prob

Hi All,

A voltmeter on the plugs for the bulb register ~12VDC for the high beams, as expected, but no voltage for the low beams (no surprise they aren't working!).  Swapping the relays for the low and high show that the low relay is fine (high beams continue to work while using it).

The only other thing I can thing of is a ground fault, and I don't know how to pursue this.  Any other suggestions on simple things I may have overlooked (e.g. low beams tied to other electrical systems?).

Any help is appreciated.  Thanks in advance,

David

Make sure that this wire is receiving a (-) when you turn on the switch. Try to jumper a wire to ground to trigger this. If it works, then you have a faulty switch.
