If you have changed the heater core and therostat on your 1991 F-150 and it still does not have heat but the hoses are getting hot what are you doing wrong?

Is your blower motor working? If so, Sounds like it is either in the control switch that controls the mix of hot and cold air. I have to turn my temp knob back and forth after it has been in one position all summer. Feel if there is any resistance when changing from cold to hot(blue to red) If none felt, its in there. Mine usually works after I have turned it back and forth a few times. You may have to take it out and clean the connections.
