Heater Problems
My 1999 f-150 5.4L is sick. But instead of having a temperature it has none at all. The problem is the heater, sometimes I have heat and cannot get it to switch to cold(usually hot outside when this happens); other times like today it's 35 degrees outside, with the blend control set to high heat it will not produce heat, I would be better off, rolling the windows down. The engine temp never moves out of normal temp range. The blend door motor is working when you turn the blend control **** from cold to hot and vise versa. However, Not sure if the blend door is actually moving. Is there a solenoid under the hood or behind the dash that could be sticking? Please help, it's cold.

Thanks for the reply
I found out what the problem is. The Blend control door is shattered at the connection to the blend actuator. I called Ford and instead of being able to buy the $4 door, they can only sell the entire heater box at $250 bucks. It's alot of work for a broken $4 door. I've been working on it for six hours now, so anyone wanting to tackle this task should reconsider. thanks again for the reply.

Take a look in the Explorer forum for a cheap fix for this problem.
