My 2000 ford expedition eddie bauer heater is blowing cold in my front vents and back vents then it has a fume smell when you turn the heater on, what can be the cause of this problem

get in touch with your local ford dealer and give them the vin #

If this means that you have no rear air at all, the problem is a cheap resistor that you can replace. Ask a parts house to find the part and show you where it is located. You can do it and it's a cheap, easy fix. If some air is blowing out of other rear vents, then the problem may be a fan and not just the resistor. Air can be blowing out of the front vents like crazy and the problem with the back can be as I described sense front and back have separate resistors.

Mixing Door

Clogged coolant line or defective heater coolant line solenoid valve?

from my experience, that is the smell of gasoline poorly burning at start up. getting into the cab that badly means that the climate control is sucking in fumes from the engine area, incredible this being a 2010. there also may be a leak at the heater core that warms up the cabin, basically coolant fluid fumes . definatly a warranty claim, something is very wrong here. pursue this with ford. battery leakage is total nonesense.

Get a tin of a good quality Radiator Sealant or a couple of packets of Ce-lit and apply them to the problem

Once you have stopped the leak go back to the stadard mix of Anti Freeze to Water

the heater is a long plastic box and the mixer door is inside of the box. The stepping motor controls the door.

Check the fuses for the blower motor and check power to the front switch to the blower.

Sound like a vent actuator is not getting vacuum or is broken.See attachment

Shelly,

Buy used parts at car-part.com. Look on page with * to find the cheapest part. Coud be your temp blend door (#2) may not be moving back and forth. Or, you are not getting hot water to the rear heater core.


You may have to crawl under the truck and feel the heater hoses to see if they are hot. You will find a group of 4 lines, 2 for heater and 2 for a/c. If hot, you know hot water is getting back to the heater core. If not, there may be a hot water vave that's not working. Not sure if EXP. has a water valve for rear.

Let us know what you you find. Good luck.
