Answer
Danny, Check the fuse and ground for the headlight unit.  It may also be inside the unit with the wiring.  The a/c flash needs a system scan, but what may be burnt is the actual control head or blower motor itseld.  The tranny may be a bad mount or bearing. The seat controls may also be the seat controller or if you hear the motor running and the seat doesnt move then you need a cable repair.  Roger
