The problem is a bad ambient air temp sensor or a broken wire to that sensor. The sensor usually is located in the front of the engine bay on the support for hood latch, between the outer grill and the radiator/condensor assemblies.

It is possible that somehow your heater core is either blocked or airlocked. Best thing to do is to feel the two hoses that go to and from the heater core when the engine is up to normal operating temperature. If one hose is hot and the other is barely warm than you have a blocked up heater core. If you feel both hoses and they are barely warm than it is possible that you have an airlock in the system. The airlock is mostly likely to occur if you have recently had your heating system worked on such as a new radiator, thermastat, etc. If both hoses are hot then it could possibly be the heater blend doors inside the heater box could be stuck in the cold position. They are controlled from the switches on the dash. When you adjust the heat setting on the dial from hot to cold or cold to hot it moves the blend doors to either let more cold air in or more heat in. Hope this was helpful. Happy motoring.
