How to Replace the 2004 Ford F-150 Air Conditioner Blower Fan
- 1). Adjust the driver’s 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 motor’s output shaft upward and off the shaft, using a set of needle-nose pliers. Pull the fan wheel off the blower motor’s shaft.
- 5). Slide the fan onto the new blower motor’s 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 motor’s 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.
