I've purchased the new blower motor, but not sure where it is located and how to go about replacing.

The blower motor is either under the dash on the passanger side of the vehicle or under the hood (firewall) on the passanger side.

1.If the vehicle is equipped with air conditioning, recover the refrigerant from the refrigerant system.
2.Disconnect and isolate the battery negative cable.
3.If the vehicle is equipped with air conditioning, the accumulator must be relocated in order to service the blower motor. This is done by loosening the accumulator retaining band screw and disconnecting the accumulator inlet tube from the evaporator outlet tube. The accumulator can then be moved far enough to access and remove the blower motor.
4.Unplug the blower motor wire harness connector.
5.Remove the three screws that secure the blower motor and wheel assembly to the heater-A/C housing.
6.Rotate and tilt the blower motor unit as needed for clearance to remove the blower motor and wheel from the heater-A/C housing.
