Right turn Signal works on top light. Left turn signal works on bottom light. Both brake lights work. Is there an easy fix.

Hi, your saying the high-mount brake lite flashes like turn signal? I'd check the ground circuit at tail lamp assembly, black wire. You could probably try a redundant ground, for testing, see if it helps anything?

Hi, I haven't seen this exact issue before. All I can do is track the circuits. Yellow wire is voltage for turn, white wire is voltage for brake, black is ground, the other one is tail lights.
