No Heat
Hello, A friend has a 2006 F250 4x4 with a 5.4. He has no heat. Blows cold through the vents on defrost or cold through the vents in dash. He says the heater hoses are warm. Any ideas?

On my 99 SD there is no valve on heater hoses and the heater core is always hot. The temperature is adjusted by electronically controlled mixer and vacuum operated flaps.
So if his system is the same as mine, the mixer failed. You can find pictorial of the system repair here https://www.ford-trucks.com/forums/8...ater-core.html
