2000 Ford Explorer Q&A
2000 Ford Explorer Question: Heater
There are a couple of reasons why your heat may not be working. 1 - Low coolant, your heater core is last thing in the coolant circuit to recieve coolant. 2 - Stuck open Thermostat 3 - Heater Blend doors not operating correctly. It is easy to determine wether the problem is inside the car or not. Check your coolant when engine is cold. If it is full, then let engine come to operating temp. and feel the two hoses coming out of the firewall. Caution, they should be HOT., if both are hot, then the problem lies inside the car, if one or neither are hot then the problem is in the coolant circuit. - Bills On Broadway

I bought vehicle without checking if the heater worked. The A/C works fine. The heater blows cold air and I do have antifreeze.
When I turn the heat on I can hear faint knocking sounds coming from the dashboard. The heater only blows cold air. The air conditioner works fine. What could the problem be?
