Defogger Problems of Chevrolet Avalanche

Hvac failure routing hot air when a/c is on and vice versa, also routing to defroster and heater works erratically.

My heating and air conditioning system does not function correctly. It has a mind of its own. It adjusts itself from hot to cold, cold to hot. It adjusts itself from low to high, high to low. Occasionally when I shut of the truck and take the key out the heating/cooling system will remain on. I can't drive in cold weather particularly in the morning or when its raining afraid that my defroster/defogger wont work because of the problem.
