Hi,

This vehicle does have a heater control valve in the system. Have you checked to make sure that it is opening to allow hot coolant to enter the heater core?

Take a look below. If you haven't checked this, try this. Start the engine and turn on the heater. Allow the engine to reach operating temperature and then shut the engine off.

Feel the heater hoses before the valve and after the valve. Both should be equally as hot. If they are, then feel the return heater hose as well at the firewall to see if it is hot.

Let me know what you find.

Take care,
Joe
