I was messing around today and ended up re-grounding my radio (82 F100). Everything works fine. Except when I move the temperature selector over to warm, the radio dies, completely looses power - all settings wiped. Move the temp selector back towards blue (cold) and it comes back on. I'm assuming there's a wire that got crammed down there and the sector switch is pulling on something. Cant for the life of me think what else it could be. I do have a LOT of wires behind the radio - 6 RCA's running to amp, rear camera RCA, Rear camera audio RCA, and a USB cable, and reverse camera power wire - all these along with the regular radio wire harness - parking brake and regular ground, accessory power, keyed on power and dimmer light wire. I'll dig into it tomorrow afternoon. Any other ideas what it could be?
I would say you are right that the HVAC control is pulling on a wire as it sounds pretty busy back there.
Even with out all you added it is busy from the factory between the radio, clock and cig. lighter wires.

I gotta say, having a backup camera with a built in microphone is a nice concept. Am able to hear verbal directions from a spotter when in reverse. I can even leave the camera turned on while driving for rear visibility (when I have the camper on there).
