How difficult is it to change a blower motor in a 2002 jeep?

My blower motor in my 2002 jeep wrangler burned out. I have changed a blower motor out in a Ford Explore before, but the motors location on the jeep is inside the vehicle as opposed to the Explorer. Is this something I can do myself, or does it require special tools and training?|||To Remove:





NOTE: The blower motor is located below the right side of the instrument panel. The blower motor can be removed without having to remove the instrument panel or the HVAC housing.





Disconnect and isolate the negative battery cable.


Remove the screws that fasten the PCM to the mounting bracket on the engine compartment side of the dash panel.


Unplug the connector for the blower motor wire harness.


Remove the screws that fasten the blower motor and wheel assembly to the HVAC housing.


Turn and tilt the blower motor unit as needed for clearance to remove the blower motor and wheel from the HVAC housing.


To Install:





NOTE: Failure to install the blower motor assembly correctly could result in an air leak or the blower motor assembly becoming completely disengaged from the HVAC housing.





Line up and install the blower motor into the HVAC housing.


Install and tighten the screws that fasten the blower motor to the HVAC housing. Tighten the mounting screws to 20 in-lb (2.2 Nm).


Plug in the connector for the blower motor wire harness.


Position the PCM to the mounting bracket on the dash panel. Install and tighten the screws that fasten the PCM to the dash panel mounting bracket.


Reconnect the negative battery cable.


Test the blower motor for proper installation by turning the blower motor speed to high and checking around the outer edges of the blower assembly for air leaks. If any air leaks are found, reinstall the blower motor.
