Acura 79310-SR3-A01 Motor Assembly, Blower (Denso)

Disconnect the cable from the negative terminal of the battery. Disable the airbag. Caution: If the radio in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. The blower unit Is located under the dash, behind the glovebox. Disconnect the electrical connector from the blower motor. Remove the three retaining screws and remove the blower motor. Insert a Jumper wire into the backside of blue/black wire of the blower motor connector and connect it to ground - the blower motor is retained by three bolts. If you're replacing the blower motor itself, separate the blower motor from the fan wheel and place the fan on the new blower motor. Installation is the reverse of removal. Check for proper operation.

Begin by checking the fuse and all connections in the circuit of Integra and 1998 and earlier Civic models. Make sure the battery is fully charged. Step 1: Turn on the ignition without starting the engine while parking the vehicle with the transmission in 'Park' and brake firmly in place. To discover where the blower issue is, connect a jumper wire to the blower motor's backside blue/black wire and ground. If the motor works during this test, the problem either lies with the blower switch itself or the resistor that controls the fan power. When the jumper wire doesn't start the motor, undo it, disconnect the motor's connector, and check the voltage between the blue/white wire and ground with a voltmeter. If you see battery power at the connector and nothing happens when you turn the motor, you need to replace the motor; if there's no battery power at all, check the blower motor relay or its wiring connections. Repeated checks of the blower resistor should be made when the blower motor operates correctly while lacking performance in specific speeds. Start by taking the resistor out of the heater case, then look for any damage to the element parts. With an ohmmeter, measure if circuits 2 and 4 through the resistor block are connected. When the result isn't correct or there's an unconnected wire, replace the blower resistor. You can get to the blower resistor beneath the glovebox by popping out the stops on both sides of the glovebox door. Lower the glovebox and unscrew two screws that hold the resistor to the heater case. Then you can pull the resistor off by hand, and reverse this process to install the new blower resistor.
