No heat in front but I have heat on the rear

[Rsowders0311]

I have heat coming from my rear vents but cool or cold air coming out of the front vents. Any help would be appreciated.

There are two heater cores. Your front is probably bad while your rear is still functioning. I had the exact opposite issue last year.

Could be heater core, probably is, but be sure blender doors are functioning properly.

First thing you want to do is check the hoses going into and out of the front heater core.
Get the engine up to operating temp and check to see if both hoses are about the same temp. If the inlet is hot and the outlet is cold then you have a blocked core if both are hot and about the same temp then your problem is with the blend door or actuators

David, theirs a front and rear heater core on all expeditions. Do as Bedrck stated, make sure your front core under hood passenger side is hot going in, and coming out. The fact the rear blows warm, you can bypass testing rear core. The rear core is located on drivers side rear to middle of vehicle behind panels. Look online, their are great videos that show you. Try flushing front first, after being sure all doors are functioning, along with aforementioned tests. Post your results.
