    New to this site today....forgive me if there is a thread on this topic that exists. I have a 2007 Tundra. When I plug my trailer in, I have running lights, I have hazard flashers. However, when I try a turn signal,left or right. I get one flash and then nothing. When I manually operate the turn signal switch up and down I get turn signal. On flash on brake lights when depressing pedal? Called dealer talked with tech, of course it's something he has never seen. Relays? Trailer module? Had anyone had this issue??
