Is the engine running at operating temperature? What does the temperature gauge showes?
Okay, I went out and ran it. Answer is: temp gauge is normal, right smack in the middle.
Common problem that the heater core gets clogged. We have had some sucess with backflushing the heater core versus replaceing it.
CK COOLANT LEVEL THEN MAKE SURE BOTH HEATER HOSES ARE HOT AT FIREWALL TO START WITH
