I finally solved this myself..... low voltage battery! Not even the mechanics that looked at it suggested a new battery. Car was dead one day, jumped it and dead again in a few days. Had new battery installed and everything started working...

Still trying, they keep saying battery is OK. But it goes dead in about 3 days, radio skips like a scratched CD, now no ac, temp, navy. But unplugged 1 clip of wires on the back radio stop skipping it fine. Now external unit is disconnected what does that mean. How do I fix that, need heat and AC help
