When I'm by myself I usually don't let my car warm up in when it's cold out before I go for a drive. But with a baby I like to get it nice and warm in the car before we load up. For some reason though I run the heat full blast but nothing but cold air comes out of the vents. The only way to get warm air to flow from the vents is to take the RPM's above idle. Sitting in a freezing car holding the RPM's above idle to get it warm is not my idea of a $25,000.00 car. My stupid Honda (which was $10,000.00 less brand new) gets really warm without any intervention from me. I've tried different combinations of HVAC setting with no luck. Does anyone else have this problem? It seems almost like no hot coolant is flowing into the heater core due to a lousy/weak water pump.
