My heat in the vehicle only blows hot air when the gas pedal is pushed. When sitting still at a stop light it then blows cold air. Is this a problem with the heater core, although I see no wet spot in the floor board, or is this a heater control valve or something else?

Do you
have the same problem?

Either low coolant level or clogged heater core.
