    Thoughts:

    Check for heat at the heater core's incoming and outgoing hoses. If there's heat, focus on the blend door and blend door actuator. If the SUV has Electronic Air Temperature Controls (EATC), run the diagnostics. Just running the diagnostics will often reset everything. Also, read your Owner's Manual on how to properly refill the radiator and purge the system of air.

    Have you had overheating problems?
