The fuse has been replaced and the blower now works but it is not blowing warm air. The thermostat has also been replaced. Could it possibly be the heater core or could it be something else?

Thanks to Jack O for the fuse location. It was burned out, so I'm assuming the blower is OK.(?)

I need you to check something. Start the engine and allow it to warm up. WIth the heater on high, feel both heater core hoses to the engine. Both should be hot.

LEt me know what you find.

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