Default Heater Is Not Working Properly

Our heater in our 07 is starting to act up. The heater works but it's not consistent. When we’re driving it works fine but as soon as we come to a stop we loose heat, it blows but no heat While sitting at a stoplight you can actually feel the tempurature drop but as soon as press on the accelerator the tempurature rises. What could be the problem?

It is your thermostat more than likely sticking open! where is the Temp gauge reading at--Im thinking it will be reading lower than normal.

Booyah,

Well you were right, it was a bad thermostat. Put a new one in and now the heater works properly.

Thanks again for your help.
