The blower is probably running when you are accelerating, but you may not have air coming out the dash vents. If there is a vac leak in the HVAC the vent control will go back to the default setting which is defrost. You may not have enough vac to keep the blend doors on the vent setting when the engine is under load.

Check for a vacuum leak. The vacuum cannister under the evap. case will crack and cause a leak. I just install a new vacuum cannister,check valve and hose going to inside of van.

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced

SOURCE: 1994 Ford E350 transmission seems like it slips at 45-55 MPH.

If you went 1k miles since that same issue occurred I would look at the transmission. A faulty torque converter, clogged fuel filter, or a clogged CAT can cause a delay in the shifting but it would happen right away not 1k miles later.

Try this article. I have the same problem and I think it is the vacuum motor that controls the door for changing from hot/cold in the rear heater box (located inside behind the L rear wheel)
