I didn't ask the question just for the sake of conversation. I asked because knowing if the rear heat works or not can determine if you have a problem with the engine's cooling system or with just the front heat unit.

There was a question floated to you about the rear heat, you've been back since it was asked but just preferred to go down the blend door route before someone who was trying to help you was able to that's all. Rather than explain what a blend door is, where it is, and how to fix it, why don't we see if that's the problem first?

Okay, I am having the same problem with my 2000 Lincoln Navigator. I thought it was my cooling system so I decided to flush it and change the thermostat, sounds pretty easy right. I flushed the system, then as I was removing the bolts for the thermostat housing the top bolt broke. I ended up spending the whole day trying to remove the broken bolt to no avail. ended up drilling a hole through the broken bolt and but a screw through to hold it for the time being. put everything back together and ended up taking the truck to my friends workshop he machined the hole for the thermostat housing and put a bigger bolt through it. So that fixed that, but the heat in the front is still cold and the rear is hot as hell. The Mech. thought it might be the heater core but he checked that and said it was good because when you turn the heat on in the begining it's hot for a couple of seconds and then gets cold. he disconnected the battery for about 20 mins and then tried the heat it was warmer then before but still not hot. He told me to take it to the dealer and have them re-set and reprogam the computer for the truck, which he said is like $87. So before I do that, just wanted to see if anyone else has encountered this problem and what solutions are out their.

I'd say either the core is still blocked or the blend door axle is broken

I just has back surgery so I haven't been able to get under the hood and look fir the problem, but I checked the rear heat and it does not work. When you first turn on the heat it will put out warm air for a few seconds then quit. Do these trucks have the vaccum operated valve in the heater line like on the older models?
