How Do I Change a Blower Motor in a 1999 Ford Ranger?

The Ford versus Chevy war has raged since the early years of automotive history. As each maker released a new style of vehicle, the other would follow see Mustang release in 1964, then Camaro release in 1967 and Corvette release in 1953, then Thunderbird release in 1955. The same happened in the 1980s, as Chevy released the American-built compact S-10 pickup in 1982, and Ford responded with its own American-built compact pickup, the Ranger, in 1983. The blower motor in the 1999 Ranger circulates the air throughout the cabin. Unlike in most other vehicles, Ford mounted the blower motor in the engine compartment. This positioning makes replacing the 1999 Rangers blower motor less of a test of flexibility than for those mounted under the dashboard.

Instructions

1

Look on the passengers side of the firewall to find the speed-control servo. Pull upward on the wiring harness-locking tab and pull the wiring harness from the servo.

Line the hole in the fan wheel up with the output shaft on the new blower motor. Slide the fan wheel onto the output shaft. Line up the new fan-retaining clip included with the new motor with the groove in the blower motor output shaft, just above the edge of the fan wheel. Press the clip into the groove until it clicks into place.

Guide the blower motor back into its mounting hole in the firewall and hand-tighten its retaining screws. Secure the blower motor by tightening its retaining screws with a ratchet and socket. Plug the wiring harness into the receptacle on the rear of the blower motor.

Reposition the speed-control servo near the firewall, so the screw hole in its bracket lines up with the screw hole in the passengers side fender. Hand-tighten the speed-control servo bracket screw, then tighten the screw from 7 to 9 foot-pounds with a torque wrench and socket. Plug the wiring harness back into the speed-control servos receptacle.
