Heater problem
2005 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 65000 miles

I worded my previous question wrong. My son said that it has coolant and runs fine, the speed does not change the temperature of the air coming out of the vents. The water temp gauge is about 1/2 up the line, so the engine is plenty warm. He is thinking maybe the knob that goes from cool to warm isn't working or something like that. It doesn't switch from cool to warm. Cool side works fine.

Do you
have the same problem?
