    Hey guys. I opened 3 fuse relay areas. I see trl left but i see no truck left. Trying to change it to see if my fast blinking stops. It causes my trl not to have a left signal. But when it blinks normal it works. Thanks

    Yes the turn signals are a logic controlled output by the sam_cab. No flasher.

    No need to take it in. It is either the left trailer turn relay malfunctioning (most common) or the left trailer turn fuse in the Sam chassis. This is a common problem
