When turning temp dial to hot.. blows hot air for 5-10 seconds then goes cold. When turning temp dial to cold... blows hot air for 5-10 seconds then goes cold.
Replaced 2 blend door actuators and resistor. Flushed coolant system including heater core. Flushed heater core again. Heater core hoses are both hot. Doesn't seem to be a coolant issue.
Fan at all levels work. Very good air flow from all areas when you turn the dials. Seems like it is only the hot/cold dial
About 90k miles
Could this be something deep in the dash (another blend door) or possibly the climate control panel?
