How to remove and install the blower motor and blower motor resistor in a Mercury Mountaineer?

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.

Mercury Mountaineer Blower Motor Resistor

The Blower Motor Resistor of the Mercury Mountaineer controls fan speed, allowing air to come into the cabin at your desired intensity for comfort year-round. The Blower Motor Resistor alters the electric resistance in the circuit, which decreases the voltage in stages, allowing the fan to spin at low, medium, or high, depending on the dashboard knob input. For the early Mountaineer SUVs, Mercury applied a simple wire-coil style Blower Motor Resistor with three fixed speeds. That was good enough for early versions. But Mercury later introduced an updated solid-state Blower Motor Resistor for later Mountaineers. Despite the fact that both designs strive to achieve the same thing, the newer component sheds bulky coils, uses transistors to dissipate heat more evenly, and can resist moisture that corroded the connectors of older Mercury models, which means more steady airflow and a longer service life for the contemporary Mountaineer. If your blower only works on high or runs at random speeds, your Mercury's Blower Motor Resistor is likely failing, and replacing it should fix fan control.

We provide a wide range of Mercury Mountaineer Blower Motor Resistor at the optimal prices. If you need Mercury Mountaineer Blower Motor Resistor, you can shop with confidence on our website.
