Replace fuse in fuse panel turn switch on for blower motor in 5 minutes fuse blows. Is this a short in wiring, or possible blower motor?
Both are possible.But it can be blower motor issue mostly.Its taking too load and that's blowing the fuse.How to Test and Replace

SOURCE: No action from Blower motor in 1993 Ford Econoline
the blower motor in under the hood on the passenger side of the van. it has three screws that hold it in place and is ususally easy to change out
SOURCE: On a 2003 Ford Econoline 3/4 ton E250, replaced
The blower is bad,or the blower switch,normaly,the blower resister only controls lower speeds,so check the switch,and the blower.
SOURCE: 5 amp fuse in passengers fuse panel keeps blowing
It also feeds the overhead console.Suspect that is were your problem is.

It's less than foot from the heater core. I would guess that either the damper doors are not on correctly or the vent hoses are not hooked up. Can you hear the blower motor running? Maybe they didn't hook the motor back up when they replaced the heater core. It takes a ground and a hot wire.I can't remember where it's at but it may be part of the same unit. Did you check the fuse?

could be a faulty switch, or bad ground. here is what you do. #1 wiring diagrahm examing this to understand how the circuit works-fuse, relay, control
device-is it a resistor switch or is there a transistor
easy to determine -resistor switch has -three settings,transistors are capable of more. #2 being that you know how to disconnect the blower motor you can check the supply side of the circuit-obtain a digital multimeter-dvom, connect the ground lead to a good known ground place the positive lead on to the positve wire at the blower motor harness (blower motor disconnected) switching fan speed on thru selections read the values of your voltmeter-low speed should be low voltage (12v system) high speed should be full 12v . if no power supplied at all a switch input test would be required (this will require ohm meter and check resistance) you will be expecting continuity, low speed will be alot of resistance, higher speed will be less resistance-max will be no resistance. if the switch is deemed good-see if there is power into the switch, if so check for continuity from switch harness to blower motor-measure the resistance-should be no less than 0.1ohms. remember when checking continuity the ciruit must be iscolated.
