Hi,
Same problem with my 1993. I just back flushed the heater core and it doubled the heat output. If that doesnt work, check the flow valve in the heater hose. Hope this helps.

There is a TSB on 1997 Econoline vans regarding a malfunctioning door in the heater. The heat is on but the door that sends the air through the heater core gets stuck in the closed position. I had to have it replaced on mine at about 40,000 miles.
