Hi and welcome to FTE! Be sure to read this to help you around this site: https://www.ford-trucks.com/forums/s...d.php?t=300691 There are also State, Provincial and International Chapters located near the bottom of the main forum page.
I am assuming the problem is with your 1997 F-150... So I will move this thread to the 1997-2003 F-150 forum. I hope they help you out.
See ya on the boards!

P.S. Your thermostat could be stuck open causing it to not heat up.
thats what i was thinking but eveyone says its fine since its not overheating.....where should my truck run ..it just above the cool....should it be closer to the middle or just under the middle..........could that be why I am not getting heat ...overcooling..thanks Melissa
It could be fine but not necessarily. A thermostat can stick either closed (which would cause overheating) or open (which could cause over cooling).
Most vehicles (at least newer ones) tend to have the arrow pointing to or near the middle. If it is near the bottom of the range the thermostat is probably stuck open.
Thermostats are fairly cheap and would be the first thing I would change. I would also recommend getting a Motorcraft (Ford) one. They have a tendency to work better (at least in my experience).
Thanks ...Beast12 ...I will try that and let you now what happens ..I have put a new blend door acuator motor on and that wasn't it so I hope you are right .. ..Thanks again Melissa
