    Hello .

    No heat inside the car .
    New thermostat just replaced .The engine warms up fine but no warm inside the car.
    When open front window heat driver side warm ,passenger side cold.

    Maybe it needs flaps calibration .
    Is there any way to self calibrate them ?

    Any opinion would be great.

    Most likely is the heater control valve / duo valve.
