Hi all. I’m having a problem with my 2011 Routan SEL that I am not smart enough to fix. The rear brake lights and turn signals work when the ignition is in the “ACC” position , but when the engine is on they do not work. The third brake light does still work. I’ve tried replacing the turn/multi-fiction signal and even replacing the TIPM, neither of which took care of it. Any thoughts on what the issue might be?? Thanks!
