Drivers side high beam is not working, left blinker doesnt work when high beams are on. Blinker works fine with low beams. Tested & confirmed 12 volts at the green wire at high beam bulb, removed headlamp assembly and checked for ohms/continuity between black wire from lamp down to bottom 3 pins of the headlamp case connector, those are fine. Connected headlamp assembly back on car and jumped black wire from high beam connector to battery ground and the high beam shines. Since I dont have any schematics, I was hoping someone would know where the ground is for drivers high beam/blinker?
