    Hi,

    I have an SRT8 2012 and I think I have an issue with the heater :

    When I start the car in the morning, with temperature set to 72 degrees, the heater is blowing quickly hot air (good) but after 30 mn driving, the heater is blowing cold air only and the only way to have hot air again is to put the temperature to the maximum.
    There is no special noise, so I was thinking there may be a temperature sensor somewhere or maybe the actuator issue described in several posts here.
    I have ordered the repair manual, and I hope to find a calibration procedure that could solve my problem.

    Any idea ?

    Thanks

    Cedric
