Any idea what the problem might be? You have an air bubble in your heater core. Did you recently have the cooling system worked on? There should be a fitting on the firewall near the heater valve which lets you bleed the heater core; if it's not immediately obvious, say the word and one of us can provide more info. Dave Hinz
