1988 Ford E350 heater
My heater in my van doesn't come near to heating the front. Its mildly bareable but it never heats up the front very well at all. The heater core isn't leaking and both hoses are getting hot, indicating coolant flow through the heater core. Anyone have any neat tips or tricks to make this heater blow some damned heat so I don't freeze this winter?
I can feel hot air coming from under the dash, but my 90 Jetta Diesel blows hotter

Run a vacuum line from the manifold to the RECIRC motor. You can find it by opening the pass. side door and moving the selector from off to MAX AC with the engine running. It should be on the bottom of the heater box inside the van.

Ok, then you have cable controlled everything. Make sure the cable for the blend door hasn't slipped. This is common and I've had it happen. Also on top of the box is the arm for the heat/cold blend door. Make sure that it's not stuck in the middle. I've had both an '83 and and '82 E350 extended passenger van with just the front heaters and both would roast you out. The '82 gave me some fits after replacing the heater core. Turns out the when we put the box back in the blend door was stuck in the middle. Once we got it to go all the way closed there was more heat than you ever needed.

If you have manual everything (w/o A/C) then you should be able to reach in through the door on the pass. side and actually touch the heater core.
One thing I have done before is remove the radio, remove the cable from the selector, put a needle nose or small screw driver through the cable end, lube the cable and move it in and out by hand. You will find just because the cable selector "seems" to move the cable, it may not if the cable is hung up. It just flexes the hot/cold cable or the selector itself.
The front pass. should be blown away from the heat and you should have enough air volume from the fan to easily blow a piece of tissue or paper towel off the dash.
Make sure leaves, pine cones, etc. have not gotten into the duct system.
Make sure the fresh air vents on the panels by the feet are in the closed position.

I never checked the fresh air panels, will do that. But I do believe my thermostat may be the 160F breed, as my temperature gauge on the dash never goes above the 1st line on Normal, and it doesn't seem to blow a termendous amount of actual heat. The blower works fine, just not as hot of air as should be coming out of it.
So as far as testing procedures go, I have confirmed that the hot/cold lever is actually moving the device it is attached to completley, and isn't stuck. I haven't looked past this, so any other tips of what I should do to check everything out 100% would be appreicated.

Also, I don't see a fresh air panel on the drivers side, only on the passenger's side, and it is in fact in the closed position. I only see one cable on top of the heater box moving something, and thats the hot/cold one.

Okay, so I've tracked down the problem, or so what I think it is.
There is no cable attached to the Defrost/Vent/Mix/ arm on the heater control. There is a cable attached to the Hot/Cold arm and it is moving the arm on the heater box.
However, I don't see a sign of another arm for the Vent/Mix/Defrost/Floor on the heater box and no sign of a cable. Does anyone have a digram of the box and where the arm should be that it is supposed to move so I can get a cable and put it on?
