2006 Honda Civic, 106,000 miles. Only blows cold air and no heat. The coolant is good and the blend door actuator is fine. What could be the problem? Thanks.

Clogged heater core. Maybe air in the system. Burp the cooling system. Does the fan work on all speeds? If not, check the heater blower resistor.
