Yes sir! all toasty here in Ohio now, just wanted to pass this knowledge on and hope it will be helpful to the next person.

Hot upper radiator hose, cold lower radiator hose and cold heater core hoses, you may have a water pump that has gone bad, mine, the propeller came un attached to the shaft and was just free spinning, it never leaked and only made a very minimal amount of noise. Its January in Ohio so it never over heated but the temp gauge would spike almost to "HOT" then return to normal. Hope this helps.

Nice follow through, we've been missing that here for a while.

I know when I came in looking for solutions I was desperate, I hope it will
make somebodys elses diagnostics easier. Thanks
I just ordered my blend door (previous issue) and followed the HeaterTreater video on You Tube. I will let you all know the outcome of that also.

I keep reading that replacing water pump has fixed the No-Heat problem on several threads. My 98 Expedition front/rear HVAC has several of the symptons I'm reading:
I have no signs of leakage of coolant anywhere
I have no noise or cavitation fron the pump
I have drained & flushed radiator, both heater cores
T-Stat has been replaced (hard to determine when it opens because engine temp remains below standard, 180 degrees); after a long drive the upper hose & heater hose are hot but not as hot as they should be.
How can I test the water pump efficiency without removing or replacing it?

...but the rear heater-A/C unit kicks on but nothing comes out of the vents? Anyone have this problem before? It is an '05 XLT

did you try switching from floor to ceiling?

Yes. There is a push button in the rear control area and it did nothing. Makes me think a faulty relay, but the DVD system still works through it.

Are you sure nothing is coming out of the floor and it just won't switch to ceiling? I as because the blend door actuators in the rear have a tendancy to break.
