So it started with the radio going off and back on. It so far as come back on for a few minutes after truck sits. When radio goes off the auto headlights come on and stay on and I lose the directional indicator on dash west,southwest ect. Those seem to be the three things effected when radio shuts off until today. When I shit truck off take key out the lights around rpm and speedometer flash off and on as well as the yellow lights at shifter. This continues with the truck off. I cleaned all the battery terminals unhooked reset and changed out all 3 fuses on the battery they looked a bit corroded. Is it a bad ground lose wire or is the Totally Integrated Power Module. Oh and the back up camera does not work but that has not worked for a long time it goes all grainy to s messed up. Any ideas

Bump.. wish I had more ideas for you but the bad ground/battery was my first guess as well.
