2008 Chevy Impala Heater Blows Cold Air. I wish everything could be this easy. I filled the reservoir to the line now I have heat on idle. The radiator and expansion tank are at the correct levels. I have a 2008 impala 39 we bought new in 2009 and has about 65k on it.
I will show in this video. I have 2006 impala that randomly will blow cold air at idle. If I get the engine above idle by reving the engine to about 1K rpm it starts to blow warm again. Ive made sure the coolant 5050 mix is filled to the line. There are many reasons your cars heater isnt working. Maybe the fan is malfunctioning.
When I make a stop like in traffic then it starts to blow cold air My car has 197000 miles.
The radiator and expansion tank are at the correct levels. Car heater does not work blowing cold air. But using the info above about how and why a heater would fail can make it a lot easier. I have a 2008 Chevy Impala LTZ with Dual heat and air controls. I wish everything could be this easy. To start this past winter the heater would blow only cold air and would not warm up until 15 minutes into a drive.
