I've got an old 97 F150 regular cab. It does burn a lil oil but doesn't seem to be wasting antifreeze. Truck has "ok" heat on floor and panels, but never seems like it get heat in the defroster for the windshield. I can run floor and defroster put my hand down by my feet and check, it's blowing hot air but at defroster the crap is cold. It's just warmer then the outside air enough to help defrost windshield when it get warmed up.

Any ideas? A/C works ok in the summer too.
