heater is not working correctly. while at idle cold air is blown, while moving hot air will come out intermittintly
just started shortly after getting oil change done. coolant is a little low, was filled within last month when oil changed.
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 firstname.lastname@example.org ATTN: Vanessa in the subject line. I look forward to your reply. Vanessa GM Customer Service
