So everything seems to be back together. I screwedu up te console a little bit when removing it, but whatever. The system seems to change settings fine. However when the system is on "mix" i barely feel any air coming out of the vents. But if i turn it on "vent", there seems to be some air coming out, not a lot, but some. Is this normal?

there is a flexible duct / tube that connects to the vents.  you have to get to it by way of the center console being disected if i recall correctly.  that flex duct is about the same diamerter as a shop vac hose but very very soft so it can kink easily.

OK would everyone go out to there TBird right now and try to ge air to come out of the vents on the front of the dash right now, please!! The mix option, mixes air between the defroster and the floor (notice how it is located in between those two settings......ever wonder why?).  To get air to come out of the vents in front of your face you MUST put your selector on vent, it really is that simple. I have had 4 of these cars they are all like that, even my 76k original mile Bird is like that. I bet if you open your owners manual it will tell you the same thing.
...and there was light!

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

That was my first impression. But after reassembly and trying it, on mix it seems more air comes out of the vents than the defrost. Thats why I asked, no need to be sarcasitc about it. Obviously there must be a leak or kinked hose somewhere...

Looking into this I can see why there is confusion here.

Cars built without A/C have both Hi/Lo and Mix positions.
On Hi/Lo the air goes to dash vents and floor.
On Mix the air goes to defrost and floor.

Cars built with A/C; 84 has just the Hi/Lo and 85 and up has just the Mix.
On these, Hi/Lo on the 84 and Mix on 85 and up, the air goes to the dash registers and the floor.

The above info is from my 84 Owners Manual and the 84,85,86 and 87 EVTMs
Sounds like you may have had some cars built without A/C

I just checked my 84 with A/C and the air goes to the dash registers and the floor in Hi/Lo.

Mix divides the air between the floor and the dash vents. So yes this is normal. On Vent all the air goes to the dash vents.

The above assumes you have factory A/C.

You know I checked the output of air coming out of my dash vents and it's not great at all!

Anyway, yes my vacuum canister is about the size of a grapefruit and it's mounted inside the fenderwell.

Okay, thats definately plugged in. I just don't understand why all of our heaters suck! I really don't. I mean should we all just weld shut out t-stats so the water gets sooo hott we have hot air? I mean I'm fed up with it and I don't know what to do.

Yes, i know the above idea is not plausible, It was a joke, sorta. lol

The heater on my 84 3.8 works great.

are both heater hoses equally hot after the engine has come up to temp? or does one remain colder than the other?

I'm a strong believer in genuine Ford thermostats. I've had problems with aftermarket ones in the past. The heat in the 85 will make you open the windows:flame:

Well I've got a question about the fan control switch? Is It normal for the connector for the fan control switch to be charred ..... I just took my dash out saturday night to replace my heater core and blower motor and when I pulled the connector loose from the fan motor switch it was completely charred.... Any help would be greatly appreciated..
