Heater problems

[stephen71]

Hello, all. I'm new to the forum and am looking forward to hanging out here.

Right now I need some help. I've got a 2000 Concorde that only blows hot air when I hit 60 mph. Slower than that, and I get cold air. But the rear-window defrost works, if that means anything. Does anyone have an idea of what might be wrong, and what it might cost to repair?

Thanks very much,

Check the coolong system level and make sure it is full.
