  Q: What are the potential issues and troubleshooting steps for blower motors on Mazda MPV?

  A:

  These vehicles have as many as three blower motors with the front blower motor circulating air to the front heating and air conditioning and the rear heater and rear air conditioning systems have different blower motors. The rear heater blower motor is fed off the front circuit of heater blower switch and resistor and the rear air conditioning blower motor has a switch and resistor. In case the speed of the blower motor is not equal to the chosen one, or the motor is not starting, possible problems may be related to bad fuse, relay, switch, blower motor resistor, blower motor or wiring. It is always a good idea to check the fuse and relay before checking the blower motor or circuit. When ignition key is in the ON position, by switching the blower switch to faulty position, one can test the voltage at the motor; when there is voltage but the motor does not start, either the ground is faulty or the motor is faulty. To check a bad ground, remove the electrical connector of the blower motor, and then connect a jumper wire to a good ground and then apply battery power and then the motor should operate, otherwise, the ground circuit is faulty. In case the suspected fan is binding, the blower motor is to be removed to check the fan. Check voltage at switch enabling blower and trouble-shoot circuit. Inspect the electrical connector and wire of heater blower motor resistor that it receives current and inspect to see whether there are any loose or corroded connections. There should be continuity across the switch terminals and in case continuity tests fail, then the switch should be replaced. To replace switches, take out the control knobs and dash panel, loosen the electrical connector and take out the blower switch, and vice versa. The procedure is the same with the rear heater and rear air conditioner blower switches and each has their particular steps.

  Q: How to access and remove the front, rear heater, and rear air conditioning blower motors on Mazda MPV?

  A:

  To remove access to the front blower motor, remove the lower panel of the passenger side trim, disconnect the electrical connector, and remove the screws that hold the motor to the case of the blower unit, and then remove the motor; the process is reverse. To remove the rear heater blower motor, use the temperature control knob to warm and open the water valve in order to drain the engine coolant, then remove the screws holding the heater unit to the floor, then remove the driver seat, decrease the electrical connector of the blower motor and all the screws holding the blower motor before proceeding to remove the screws holding the blower motor in place mostly, and verify the amount of coolant after installation. In the case of rear air conditioning blower motor, have the air conditioning system discharged at a service station, disconnection of negative battery cable, left rear side trim panel, high and low pressure refrigerant lines of the cooling unit, and all electric connection of the cooling unit including the connector of the blower motor; after that remove the nuts and bolts of the rear cooling unit and remove the cooling unit and then screws that hold the blower-motor.
