Asked by Jan 06, 2015 at 09:04 PM about the 2007 Pontiac Grand Prix Base

Question type: Maintenance & Repair

I have a 2007 Pontiac Grand Prix and while it idles and i turn on the heater it works fine,
but as soon as i start moving, it starts blowing cold air. I changed the thermostat, it has
coolant, the hoses get hot and i even change the  climate control module and still
nothing. Could anyone help figure out what this could be?

Make sure the coolant level is full, then bleed the air out of the system. There are some good YouTube videos on the subject.
