I have a 2013 lariat with Sony sound system and 8 inch sync radio. Truck has a sub, and aftermarket mirrors and headlights. My radio only works if you turn the truck on after everything is completely off if you turn it on off and then on again the radio doesn’t work. The climate control doesn’t work unless you unplug and replug in the fcim and when it does start working the fan eventually stops blowing as if it lost power or is not receiving enough power. replaced apim, radio box, screen, and fcim and none of it worked. I need help on what could be causing this problem. We have checked wires and haven’t found anything.
