Diagnose And Replace A/C Blower Motor On Ford E-Series with Pictures

A/C – Heat Not Blowing Any Air

This is the same For the E-150/250/350/450

This Procedure is very similar in other vehicles. Usually the only thing that changes is the location of the blower motor. Some may be more difficult to access. 

On the Ford E-Series the Front Blower motor is pretty simple to change.

Costs

This Blower Motor MSRP from Advance Auto Parts is $91.99 + Tax but I paid $65.26 + Tax and received about $6.90 rewards credit towards future purchases.

Tools Needed 

• Test Light
• Ratchet
  • extension
  • swivel (makes it easier)
  • socket sizes
    • 8mm
    • 10mm
    • 13mm

I have changed plenty of these on this the Ford E-Series and this takes me about 20-30 Minutes.

Step One – Diagnosing 

Even though this tutorial is on how to replace the Blower Motor Let’s make sure that it needs replacing in the first place. Some of these steps in diagnosing may seem a bit obvious but they may be a bit easy to over look. 

1. Make sure you check the vent controls on all settings, low, medium, and high. These blower motors have a resistor and sometimes when these go bad only certain speeds will not work. If air begins to blow though the vents at any speeds, usually this is the resistor failure. 
2. Check all the fuses. 
3. With a test light make sure that there is ground and power at the blower motor connector (make sure the vent setting are set to ON). 

Using a Test Light Check For Power and Ground at the Blower Motor Connector.

It is Important to check both because a ground wire can also be broken causing the blower motor not to work.

Step Two – Replacing the Blower Motor

This procedure is the same for most Ford E-Series.

1. Remove the battery. 2 Terminals(2 10mm bolts just lose do not remove completely) and Battery holder(1 long 8mm bolt).

• 

2. Remove the 4 (13mm) bolts that hold the battery Tray 

3. Remove 2  (10mm) bolts that hold the A/C Drier. This just helps let you get the blower motor in and out easier. The fins on the blower motor are plastic and the extra room keeps you from putting force on them. (don’t drop the bolts they can fall in a difficult to reach area)Also do not force the Drier too much. You do not want to break an A/C Line.

4. Remove the blower motor connector and rubber vent tube to the motor. 

• 

5. Remove the 8mm bolts that are around the Blower Motor.

• 

6. With out forcing or bending the fan blades, remove the old motor from the vehicle. Note you may need to turn and angle the motor a bit to find just the perfect position that motor comes out. 

• 

7. Make sure that the new and old blower motors are the same. Your want to make sure the fins on the blower motor are facing the same way. You also want to insure that the connector are the same. Note that there may be some differences in new parts. But, make sure that the connectors and screw holes are the same. 

Here you can see that the connectors look a bit different. But, the plugs ends are the same.

8. Now that you insured that the new part is the correct one. Place the seal on the new motor. This is like a large sticker that only fits one way. So, make sure that you line the holes and shapes properly. Also remove the rubber vent hose from the old motor and place it on the new blower motor.

• 

• 

9. With out using force place the new blower motor into position and replace all the 8mm bolts that hold the blower motor in place. Remember it only fits one way, so you may need to turn the blower motor to make sure all the holes line up. Also do not force the Drier too much. You do not want to break an A/C Line.

10. Replace the 2 10mm bolts that hold the A/C Drier. (don’t drop the bolts they can fall in a difficult to reach area)

11. Connect the Blower motor and rubber vent hose.

12. Replace the battery tray(4 13mm bolts), battery (2 10mm terminals), and battery holder (1 8mm bolt)

13. Enjoy your A/C!
