either your heater core is shot or the temperature switch in dash needs replacing I had a 1986 Nissian Pickup that had the same problem when I purchased it back in 1988 in Phoenix, AZ.
I figured this out driving thru the Rocky Mountians on my way to Ft. Knox, KY. The heater had been running for about an hour and I was still cold (good for staying awake). I looked under the hood and found the problem.
I hooked it up again and started to drive again and in a couple minutes, I could smell Antifreeze.
The old owner had by-passed the heater core because it had a leak. Someone may have done the same thing to your Ford. Hope this helps. Good Luck and Remember.

There are several common heater problems for a 1997 f150. A stopped up or leaking heater core, bad thermostat or clogged up blower fan housing all can cause heat problems.
The variable resistor has probably gone bad
How do I locate the heater blend door actuator in a Ford f150 pickup
The head gasket is about to blow.....Typical ford..

There are a couple of a reasons why a 1994 Ford F150 truck will not start. The truck may have a dead battery or the spark plugs need to be replaced.
The headlights in the Ford F150 may have stopped working due to a bad fuse or bulb. Check these and if it doesn't fix the problem visit a mechanic.
It's the block heater. I had the same problem.
A blown fuse would cause the hazard lights not to work on the 1994 Ford F150. It could also be blown bulbs causing the lights not to work.
The most common cause of this failure is a broken blend door. Check heatertreater.net for diagnostic information and an inexpensive fix.
That would be a bad fuel pump in that tank
Check out the Google Images and search for '93 Ford F150 heater hose'. you should find it there.
switch, fuse, wiring, connector...
for the pipe to freeze and crack
Check all your grounds
Inline in one heater hose underhood near the HVAC box (right hand side underhood.)
I have to believe that it would be a bad wheel cylinder that controls the back brakes.
Dealer? Salvage Yard? e-bay? Craig's list? Hemmings?
You probably have a leaking heater core.
The heater flap, or blend door, is difficult to replace with OEM parts supplied from Ford. There is an aftermarket kit that makes the job and cost significantly easier at heatertreater.net or on the Ebay listing.
Most likely it would be a blown fuse in the fuse block.
it is on the dash board by the heater and ac. it says front fuel rear.
