2000 Dakota Club Cab 2WD 3.9 V6. Driver side low beam no longer turns on high beams work on both sides but no lowbeam on driver side. Changed bulb cleaned connections check fuses every thing checks out. Anything else I should look for? maybe a hidden fuse written under a different name which I've seen on this fourm.

 

The bulb is always supplied +12v from fuse B in the PDC off the battery. Fuse G is for the passenger side.
The ground side is switched.

Check the socket again for a bad ground connection or a damage splice. Both headlight share the same grounds.
