there is 2 low beam fuses , see if theres power at these 2 fuses.
the ground side of the headlights are controled by the body control module . the module may be bad so we need to do some tests .
Ok, got 12v at the fuses, and I can hear the headlight relay click when I turn on the headlight switch on the turn indicator stalk. Do you have higher rez versions of the wiring diagrams? these are hard to read.
