- I have a 1993 f250 5.8 with 99k miles and have no heat. I looked to see if all of the actuators work and they do. The only thing I can think is wrong is the temperature control knob can be moved all around. And if it is that could somebody find some information on how to replace that knob.

Did you feel if both heater hoses are hot?
information on how to replace that knob.
I doubt you'll find a new one, so your best bet is to repair or find one at the junkyard
