    working on 2018 Cascadia, start the truck up and the left rear tail light ,both side markers, center 3 visor markers and both hood markers start blinking. almost like its in a security mode. turn on the left turn and both tail light flash back and forth. does this truck have a lighting controller or does the s sam module control the lights. any ideas would be appreciated

    Read the thread:

    2011 Cascadia SERIOUS electrical problem URGENT help needed please!

    They mention basicly the same thing. I think it ended up being a bad power disconnect switch. I’m not familiar with cascadia, but sounded like it was around the batteries??? Maybe??
