SOURCE: 1997 F150 heater problem

your problem is caused by the air temperature control blend door actuator motor being defective, the little motor moves the door that gives either hot air or cold air or a blend of the 2.

SOURCE: 1998 ford f150- heat issue

There is no heater valve on a 1998 ford F-150. The hoses for the heater lead directly from the engine and go to the heater case. PS The heater doors are all vacuum controlled so you might wanna look under the dash for any lines that might be disconnected

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.

SOURCE: 1999 Ford Taurus, no heat.

Try checking the two pipes that go into and come out of the heater matrix, is one of them hot? if it is there is an air lock within the matrix, Also is the thermostat opening fully? Sorry i know you said you have changed it twice already but take it out check settings when it should open and close, then boil some water and test the thermostat

2001 VW Beetle 2.0 heater won t heat up


If you flushed the coolant with the thermostat in, chances are you didn't flush the coolant. Regardless, it's easiest to check the controls inside first. Does the blower fan work? Does the air flow change from floor to vent, to dash as it's supposed to? Does the A/C change temps when knob is turned from cold to hot? Post results.

Luke warm heat in a 2002 expediton


Start with Flushing out your cooling system. Flush it out with Preston Radiator flush, you have your preference of ether the super flush which takes 3-6 hours or the 10 min flush which is good if you don't have the time to flush out your cooling system.

After you have flushed out your cooling system, replace your thermostat and you should be good for another cold winter driving. What happens is that after a few years of the coolant not being serviced, the coolant crystallizes and clogs up the heater core and radiator causing poor circulation. Poor circulation will cause poor heat and or overheating issues to the engine.

Before you go through all that inspect to make sure you have the right amount of coolant in your cooling system.

Good luck and thank you for using fixya

1997 ford expedition has no heat. blower works replaced thermostat. now what


Under the middle of the dash is a part called a blend door actuator it is located between the floor board and the heater housing. It control the door that opens and closes allowing heat to exchange.These go out all the time.

No heat is there a fuse 2003 f250 is there a fuse for heater


i don't know realy if there is a fuse (though i doubt it) but issues with heatting may be this will help.

If the carpet under the heater core is damp, or if antifreeze vapor or steam is coming through the vents, the heater core is leaking.
Remove it and install a new unit (most radiator shops will not repair a leaking heater core.
If the air coming out of the heater vents isn't hot, the problem could stem from any of the following causes:
  • The thermostat is stuck open, previnting the engine coolant from warming enough to carry heat to the heater core. Replace the thermostat.
  • There is a blockage in the system, Preventing the flow of coolant through heater core. Feel both heater hoses the firewall. They should be hot.if one of them is cold, there is an obstruction in one of the hoses or in the heater core,or the heater control valve is shut. Detach the hoses and back flush the heater core with a water hose. If the heater core is clear but circulation is impeded, remove the two hoses and flush them out with a water hose.
  • If flushing fails to remove the blockage from the heater core, the coremust replaced.

Only blows cold air from vents even when temperature gauge set to red for hot air.


Temperature gauge should not be in the red unless you are talking about the temp control. Check hoses to heater core for a temp difference once the vehicle has reached operating temp. If a big differenced is noticed heater core may be plugged and may have to be flushed or replaced. Do the same with radiator hoses could also be a thermostat

2001 expedition heater does not heat well


I would flush the whole system with radiater flush then replace with new coolant. But make sure the heater is set to full heat when you flush it ( while driving around the block with flush in it) so the small radiater that has the hot water flowing through it gets flushed too. It may have some build up in it stopping the full flow of heated water/coolant through. If it is bad enough may need to remove and spray out the rubber hoses from the motor to the heater core, and possibly remove the heater core and hose it out to make it flow better and therefore increase the heating ability. Hope this helps.
