    Hello kristyd,

    The troubleshooting section of our manual #38036 addresses this kind of concern. You most likely have a coolant issue.

    Hi kristyd,

    Although we can't diagnose problems from a remote location, we can tell you this: If your coolant level is too low, the engine will overheat AND you won't get any hot air from your heater, because no coolant is circulating through the heater core. So that's one possibility.
