'98 Ford Explorer, No Heat

Q: I have a '98 Eddie Bauer Edition Ford Explorer. A few days ago the heater stopped working. The fan works well but there is no heat whatsoever even at 90 degrees. It is no fun to have this problem at this time in the Northeast.

- Dilmer D.

A: Is the engine heating up to the correct operating temperature? Is the coolant at the correct level? Are both hoses to the heater core hot to the touch? If so, I would suggest having the hot air blend door and actuator in the heater box inspected. If you're lucky the actuator (which is an electric motor) will be broken or it will not be receiving a signal to alter the position of the blend door. The fix will be a replacement actuator or heater control module. If automotive deities are out for fun at your expense, the blend door will be cracked. A broken blend door doesn't sound like much, but that blend door comes with a whole lot of luggage. A replacement blend door, which is new and improved, has a redesigned heater box with it. It takes about 6 hours to install the replacement heater box assembly and the cost of the heater box is in competition with the labor cost.
