Q: How do you remove the blower motor in the engine bay and install it back on Ford Explorer?
A: The blower motor can be found on the right-hand side of the engine compartment. Take off the negative terminal wire from the battery. Remove the air cleaner for 1994 and earlier models. Push down on the electrical connector locking tab and disconnect that blower motor connector. Disconnect the small rubber cooling tube model without air conditioner from the blower motor. For models with air conditioning, remove a single nut from the bottom plenum. Disconnect the electrical connector from the blower motor resistor, vacuum hose from the check valve, and vacuum line from the intake manifold. Remove three screws that hold the blower motor to the heater blower assembly. Pull the blower motor out of the heater assembly. Remove the push nut on the motor shaft and remove the wheel if necessary. To install, reverse the above steps of removal process. Ensure fully seating electrical connector so it clicks into position.
Q: How to troubleshoot the blower motor on Ford Explorer?
A: To troubleshoot the blower motor, start by checking the fuse and circuit connections for looseness or corrosion. Ensure the battery is fully charged and, with the ignition in the On position, switch the heater controls to FLOOR and test the blower at different speeds. The blower motor resistor assembly, mounted next to the blower motor, contains resistor elements for low and medium speeds. Visually check the thermal limiter for damage and test the resistor block for continuity; replace if necessary. Backprobe the pink/white wire at the blower motor for voltage. If voltage is present but the blower doesn't operate, check the ground circuit. Test the blower speed switch for continuity in different positions. Locate the blower motor relay behind the right headlight and check resistance; replace if needed. For models with a rear air circulation unit, remove the console trim, disconnect electrical connectors, and pull the console and blower housing out to access the blower motor for the rear seats.
