My heater will turn on and blow but will not get hot. My thermostat is digital so I will turn it all the way up and it still won't get hot. I am not sure what is wrong. Is it the heater core or something else.

Hi there, with the engine warm and the heater on feel the two heater hoses going into the cabin, if one is not as hot as the other you will have a faulty heater control unit or a blocked core, check this out first.

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