Now, the funny part is that when I pull the signal lever toward me like flashing high beams, they will light up, but when I push it away from me to use high beams, they will not light up.

check fuses 6-15-16-18-24-26 in junction box by steering wheel under dash and fuse 11 by battery junction box. these are all for the headlights. it could also be a module, or switch.

This sounds like the the relay in the LCM Module. Get a refurb LCM or replace the Relay part number NEC EQ1-11111s.
