How to remove dashboard to a e250 ford to replace fan switch

1 Open the hood, and remove the cover from the fuse block. Locate the fuse numbered "105,"and remove it with a fuse puller.

2 Install a replacement 40-amp fuse in slot "105," and reattach the fuse block cover. If the blower is still malfunctioning, you may need to replace the motor.

3 Open the passenger's side front door, and locate the blower underneath the right side of the dashboard. Remove the three screws securing it to the vehicle.

4 Remove the three screws securing the motor to the fan blower, and install a replacement motor.

5 Reinstall all of the screws, and close the door.

There is a resistor block that controls the speed of the fan...it is usually located somewhere near the fan and has 3-6 wires on it...it may be shorted and needs replacement

The most important job is to remove the main dash board as the blower fan is loccated beneath the dashboard. So armed with the right told and a help you must carefully remove the screws to pull the dashboard.
Now the blower assembly is fitted under this as you will be able to disconnect the wiring connectors to remove the fan motor.
replace and refit in the sequence you had removed making sure the connectors are correct and fitting.

easier to use a 12 volt test light on connector to blower motor to see if power is getting there.
If not, take switch out and test or replace.
If power is there, replace blower motor. (you can take it out and use short jumper wires to the battery to make sure it doesn't work--as i think you were suggesting you wanted to do)

Here are steps to access the motor:

Remove the footwell lower trim panel.

1. Open the glove compartment.
2. Remove the footwell vent air duct.
3. Pull off the hose.
4. Close the glove compartment.
5. Disconnect the blower motor electrical connector.

Please let me know if you have any questions.

The blower is bad,or the blower switch,normaly,the blower resister only controls lower speeds,so check the switch,and the blower.

I would check the blower motor resistor 1st

ya just pry off the black plastic with a screwdriver. and then u will see the screws that need 2 come off

you want to remove the AC fan belt and buy a new belt to replace the old one so that you do not lose horse power form the parisitic darin caused by the belt and compressor.

replace your fun

You need to check the ressistor under the dashboard, behind the glove box if that isn't it then replace the switch which you can get cheapier at a salvage yard or on ebay. I just did this and anew switch is $55.00 at my local Ford dealer.
