It could be the thermostat sticking open. Just a thought. It happen to my old f-150.

Exactly. Same with my 1993 F-150 that I have now, thermostat stayed open and the cold water just kept circulating through the engine keeping it from warming up very much. I would start there.

No heat is almost always heater core, blower motor not pushing, or thermostat

Try a new thermostat first. If this is the first year that you have driven this car in the cool weather, check to see if the previous owner installed a 160 degree thermostat. It was a popular 'mod' a few years ago.
