The heater blows cold air when the engine is idling. Plenty of hot air comes out when the engine is above an idle.
I drained cooling system last fall and replaced with Prestone/water. Have checked and radiator is full, although I didn't put any prestone in the overflow container last fall. I have since topped the overflow container up to the fill mark.
Temperature gauge is normal. Everything seems to be fine, just no hot air when engine speed drops to an idle.
Your advise is appreciated.
have the same problem?
