heater is not working correctly. while at idle cold air is blown, while moving hot air will come out intermittintly

Air pocket in the cooling system is a possibility. Clogged heater core is another.

Hi John, I would suggest having your Pontiac serviced at your GM dealership as they would be the best resource to diagnosing the issue you're having with your vehicle. If you would like to private message me your VIN, I could research to see if there are any possible recalls or special coverages related to the what you're experiencing. If so, private message me at socialmedia@gm.com ATTN: Vanessa in the subject line. I look forward to your reply. Vanessa GM Customer Service

Did you ever find the solution? I have the same problem and the same model you have. Please comment!

me to when I am at a stop my heater does not work? any suggestions?

Have you checked the heater core?

Any solutions found? My 2007 pontiac g6 gt has no power steering (only one not included in recall) and now no heat while idling! Brrrrrrrr

I have a 2006 Pontiac G6, the heater will stay running when engine is turned off and key taken out of ignition. Anyone know what's going on

If the cars heat is not working and it’s a 2009. You have a cracked radiator. My brother in law just fixed mine.
