Heat doesn't work '07 GT

[TJNAPPY]

So, everything else on the Climate Control panel works, except the Heat. I set it to 90, normal car air blows out and I tried all the setting combinations. Air Conditioner still works excellent.
Any advice on what's wrong? Thanks

flush the heater core. its air bound likely.

I'm totally with BillBoost, because, he's always right

Had a problem like this on a 98 gtp. But it would blow cold air only on the passenger when set to heat on dual climate control. Turns out it was a faulty blend door actuator, the plastic gears inside were binding. If only one side is blowing cold it's the actuator. If both sides are cold it's probably a clogged heater core like Scotty said I mean Bill

Ok, thanks. I'm taking it in to the mechanic Saturday and will let you know what was wrong. Thanks.
