ok thanks.you will have to access the headlight switch connector at the back of it.flash the high beams and monitor the light green wire coming out of it. this wire will also connect into 2 pink wires.this is a ground operated wire which operates the high beams.if you are getting a ground signal out of the switch to that wire when pulling back but not when pushing forward than the switch is faulty and will require replacing.i have included a wiring diagram for you as an attachment.let me know how you make out!
