My 2002 Ford F150 blows barely warm air. I have flushed the fluid, changed the thermostat, and checked blend door operation, but no change. The upper heater hose is warm, but I still do not get heat regardless of the RPM of the engine, no heat. The A/C works perfectly.
I'm thinking there is air in the system like my Lincoln. I ran the front end up on ramps then loosened the reservoir cap. Then I squeezed the upper radiator hose and the air bubbled up into the reservoir. Refill the reservoir fluid to level. Tighten down the cap. Or, don't always trust the new thermostat. I have returned so called new ones because they were defective.

I have a 1994 Ford 150 truck. The heater barely gets warm air into the truck. I have had the heater core and radiator flushed. What else should we do?
By Dixie M.
Try changing the thermostat and double check the heater hoses to make sure they are not clogged. Also, there may be a vacuum operated valve in line with the heater hose that turns the heater off when the air conditioning is in use.
I have a Ford 2005 F150 with no heat. I changed the resister and the blower motor. When I turn the dials I hear something moving, but no heat. Can someone please help?
Thank you very much. I will check
I have a 2011 Ford F150. The heater/AC fan is turning off and intermittently running. The AC goes off. If I turn the switch off and wait 5 - 10 minutes it works for a short time and then shuts off again.
Any ideas?A lot of times this could deal with the radiator in the truck, the cooling fan, or the fan belt. If you are having this issue check to make sure the fan belts are working correctly and there isn't a problem. Also, check the cooling system of the truck and make sure you have enough cooling fluid in the motor.
I have no heat in my truck. I have flushed the heater core and still no heat. I did change my thermostat and both hoses are hot going in and out of the core, but it is not blowing heat in the truck.

I've got a 2000 F150 with the same issue. I am flushing the heater core this weekend as I believe I have a partially clogged core.
Also, I'm doing the air blend door actuator, sounds like the air blend door actuator may be your issue.
My Ford F-150 stop blowing a/c and heat. The blower still blows, but just air.
Here are a few things that you should check:
My 2001 Ford 150xl v6 heater was making a flapping sound for awhile and has stopped. It stopped blowing heat, but would work by tapping the heater now there is no heat. What is the problem?
By RD
Check your heater blend door motor.
The heater fan motor on my 1993 F150 runs, but no air comes out of floor vent, defrost, or panel vents.
I have a 2004 Lariat F150. My blower is working fine, but my temp will only work at 90 degrees for the heater and the cold air is working fine. Can anyone tell me what the problem is?
Some reasons the heater may not be working.
I have a 2009 Ford F-150. My heater does not blow hot air when the heater is on. The blower is working fine. Air comes out both sides. The driver side is just a little warmer than the passenger side.

I have a 2009 F150 truck, the right side works fine, it blows hot and cold, but the driver's side only blows hot; it won't switch to cold.

I have a 2000 Ford F-150. The heater is not blowing air out of the vents. I changed the heater core, switch, and resistor. It did not fix anything. I can feel heat and cold air barely coming out of openings, just not blowing it out.

I have a 2009 Ford F150; all I got is cold air, no hot air. What could be wrong? Please help.

Why does the air in my 95 F 150 only come out of defrost vent no matter where the air directional knob is?
