2000 expedition heat problem
Hey guys, my wifes 2000 expedition has a problem with the heater, it has very little or intermittent heat, before I start looking is there a common problem I should look for? It has controls for the rear if that matters. Thanks for your suggestions.

There are many threads and post regarding the broken blend door hand how to repair it. Use the search function above.
In the mean time you could set the rear heat on high and that will help a lot.

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.

He seems to want to go right for the dash pull, rather than take a second to properly diagnose it. Let him do it.

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

The most common cause is the blend door. Do a search and you will find many posts on it and how to repair it. At a dealer you are looking at over $1000, a radiator shop might be as low as $500.

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?
