Pontiac Grand Prix Heater Problem
Minimal hot air coming out of vents. I have flushed the system including the heater core, changed thermostat, checked the three electonic valves for recir, heat flap and vent positions and they all work. Any ideas?

Are both heater core hoses getting hot? IF so (and the blend air door is working), you should have heat. If only one side is hot, chances are you still need to flush the heater core again.
