As you know the brakes/rear turn signals/rear flashers use the same large filaments in the rear 1157 bulbs so since the brake lights and turn signals work that means you are good from the turn signal switch/harness rearward. Need continuity/fire between the white wire on the flasher switch connector over to the white wire on the turn signal/brake harness connector under the column. This is the circuit that powers the rear flashers (both brake lights) from the flasher switch
