Yep-that did it. No idea there was another series of fuses behind that change container(that I've never even opened since owning the truck from July). I was pretty sure it was just a fuse.
So, for clarification for others that might encounter this issue....
This whole ordeal is originated from a busted up tail light assy on a trailer I was pulling(from one of our bikes falling over and practically destroying the left tail light assy). The lamp/wire assy shorted to ground back there and caused two fuses to blow.
TAIL TOW under the hood in the fuse box(which caused my cruise light to blink after disengaged, and then prohibited me from shifting out of PARK into drive...btw, that was solved temporarily by pulling the square plastic plug off the shift pedestal-fwd left area)...then, the fuse under the little coin/storage box, left of steering column, down- right in front of your left knee area. Replacing that
fuse fixed the inop truck rear tail lights/front marker lights, as well as interior lighting issues, ie, the radio select keys below screen read out, climate control knobs/area and the shifter illumination down on pedestal.
Hope this helps someone else..........
And thank you Randy. Appreciate it.
