Are you refering to your temp gauge? Or is your heater not blowing hot air? If it's the heater, does it blow warm air? If it does, try switching your selector to recycle air instead of fresh air. My girl's sportage wasn't able to get warm(the heater) over the weekend and she switched the selector and it warmed up fast! Apparently, it was so cold that the heating coils couldn't heat the incoming air enough. <img src="/forums/images/graemlins/shocked.gif" alt="" />
