Q: How to remove and install blower motors and resistors in a Mercury Mountaineer?
A: Remove the lower trim panel below the glovebox and the electronic shift control module if applicable. Disconnect the connector from the blower motor resistor, remove screws, and extract the resistor. To install, reverse the process. For the rear resistor, remove the left rear quarter trim panel. Detach the connector, remove screws, and extract the resistor. Installation is the reverse process. For the front blower motor, remove the lower trim panel, the vacuum tank screw, and separate the tank from the heat control unit. Disconnect the connector, remove screws, and extract the motor. For the rear motor, remove the left rear quarter trim panel, disconnect the hose and connector, remove screws, and extract the motor. Installation is the reverse process.
