    I started to have some issues with my cascadia : when i turn climate control on while driving last time ( yesterday ) it was working for 15 min . Fan still worked at the set speed but unit controller itself wasn't reacting for fan speed change or air flow change direction . Controller is illuminated though . At the same time with controller radio and mirror heat stop working as well . It starts working only after truck restart .... But at night while idling all working normally .
    Any thoughts ?!
    Its 2013 cascadia glider , engine put 50k miles ago and everything else is working flawlessly .
    Ps : can bad alternator do this ? I know mine is bad and most of the time i drive display reads anywhere from 11.7 to 12.1 , while idling at night - 12.4-5
