Q: How Do I Replace or Service the Heater, A/C Switch,Blower Motor and Control Components on a Honda Prelude?A: The SRS system should always be disarmed before performing dash repairs. On Accord and Prelude models, removing the blower motor might require taking out the A/C evaporator. Only MVAC trained and EPA certified technicians should service A/C components due to legal implications. For the Accord 1996-97 models, remove the negative battery cable, glove box door and frame, and heater duct. Detach electrical connectors from the blower motor, remove fasteners, and take the motor out downwards. For the Prelude 1996 models, detach the negative battery cable, take out the glove box and frame, and remove the heater duct. Disconnect all electrical connections from the blower motor, remove the blower resistor, recirculation motor, and two nuts from the bolts. For the heater core, take your vehicle to an approved facility and discharge the A/C system. Drain the engine coolant, remove the heater control valve, and take out the heater hoses. For the heater water control valve, turn the ignition switch to ON, set the heater temperature to full hot, then switch OFF. Drain the coolant, or clamp the two heater hoses. Remove the control valve cable clamp and cable, and take out the heater hoses and the control valve. For the control panel, remove the center trim panel, detach the air mix control cable from the heater unit, remove panel retaining screws, and pull the heater control panel from the dash.
