I have the same problem, as im driving i have some heat but as soon as i stop heat dwindles. my suspicions are like Denis said making sure the heater core is getting good circulation or it could be a dying water pump. This is what else happens: after driving when i shut it off i hear a bubbling (sounds like the heater core has air too but im not 100% sure), also i may have over filled the coolant bucket which may have prevented the bleeding out of the heater core if air is the problem. im too poor and cheep to go to a garage and have it taken care of so im either gonna have to try fixing it my self or bite the bullet on this one. if anyone has any other suggestions please post. (its not the air mixing flap or anything else in the duct work) 04 ford explorer xlt with rear heating

1st make sure the heated core is getting hot, do this by feeling the hoses under the hood that supply hot coolant to the core, if the inlet and outlet are hot then the core has circulation and is not the problem, check this and let me know what you find.

Ford f150 xlt, blower fan won't blow ac into cab of truck can feel cold air when on highway. But fan not working. Help?

Check to see if the blower works with the heater on. Turn the control to heat and see if the fan works. First check the fuse for the blower. If the fuse is good and the blower does not work with heat on , the blower may be bad or the speed resistor maybe bad.

I have a 2000 Ford Explorer XLT with the 302 V8. The blower does not work at all in the front dash, however the blower in the center armrest for the rear seat passengers, blows cold and normal. On

Hi, the problem could be the motor, controller, or resistor. You will have to troubleshoot using a volt/ohmmeter. If you have a meter and are willing to troubleshoot, I can send a procedure.

There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

Front heat works, but rear blows cold air only

With your front heat working the most likely cause for the rear heat not to work is that there is an obstruction in the line that is preventing the warm coolant to get to the rear heater core or the rear heater core itself is plugged and not circulating. Another possible cause could be low coolant level where the system has enough coolant to provide the front system with enought warm coolant but not the rear system. Hope this helps
