How to Replace the 2004 Ford F-150 Air Conditioner Blower Fan

The 2004 model year marked the sixth generation for Fords best-selling pickup, the F-150. This generational change brought the classic truck form back to the F-150 badge, as Ford eliminated the bubble body style the F-150 had used since 1997. The 2004 F-150 used a small electric fan to circulate the heated or cooled air throughout its cabin. Replacing this blower motor is not overly difficult, but it does require care while removing the A-pillar trim panel.

Instructions

1

Adjust the drivers seat as far back as it will go. Pull outward on the lower, right-side A-pillar trim to unfasten its retaining clips and pull it out of the pickup; notice that the kick panel is a part of this panel.

2

Grab the carpeting that routes under the dashboard and pull it downward, exposing the blower motor.

3

Pull upward on the locking tab on the blower motor wiring harness, and pull the wiring harness from the blower motor. Remove the three blower motor screws with a ratchet and socket, and lower the blower motor out of the HVAC box.

4

Pull the clip holding the fan wheel to the blower motors output shaft upward and off the shaft, using a set of needle-nose pliers. Pull the fan wheel off the blower motors shaft.

5

Slide the fan onto the new blower motors shaft until it reaches the base of the shaft. Line up a new fan-retaining clip -- included with the blower motor -- with the groove in the motors shaft, just above the fan. Press the clip into the groove until it seats into place.

6

Guide the fan and blower motor back into the HVAC box and hand-tighten its retaining screws. Tighten the blower motor screws with a ratchet and socket. Plug the wiring harness into the receptacle on the new blower motor.

7

Pull the carpeting back up into place. Set the right-side A-pillar trim panel into place, lining up its retaining clips with the slots in the A-pillar. Press the panel onto the A-pillar until the clips snap into place in the slots.
