As soon as winter hit we found that the heater blows cold air. The thermostat has been replaced and still no heat. What could go wrong with this system? I am freezing!

Could be a clogged-up hose or the heater core, heater contol valve, air/blend door stuck close.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
