  Q: How to remove and install the Blower Motor components on Volvo 780?

  A:

  To remove and install components in the 240 Series and Coupe, begin by disconnecting the negative battery cable before removing the sound insulation and side panels around the radio, if any. Next, remove the control panel and center console, center air vents, cable, and electrical connectors of the clock, glove compartment, and air ducts. On the right side, remove the air ducts and disconnect vacuum hoses from the shutter actuators and fold back the floor mat to access the rear floor duct screw and move the duct aside. Remove the outer blower motor housing and blower motor wheel, remembering that there might be support under the glove compartment that need to be removed for access. Disconnect the blower motor switch and electrical leads and repeat for the air ducts and vacuum hoses on the left side. Remove the inner blower motor casing, vacuum hose, electrical connector, and blower motor. If it needs to be replaced, a modified unit is available for specific instructions. For installation, you have to clean the heater housing and then install the blower motor, electrical connector, vacuum hose and inner casing before you install the blower motor wheel and outer casing. Reinstall the air duct that vents to the outside through the rear of the floor and the mat of the floor, connect air ducts and vacuum hoses, and re-connect the electrical leads to the blower motor switch. Finally, reinstall the center air vents, control panel, center console, sound insulation and side panels and reconnect the negative battery cable before testing the operation of the system. For 740 Series, it is removing the lower glove box panel, unfastening and removing the electrical connector from the blower motor, removing the blower motor assembly, and cleaning and installing parts. In the 760, 760, 900 Series and S90/V90 with automatic climate control, the procedure involves removing the battery, the lower glove box panel, instep molding, control unit after cleaning and re-installation of the blower motor and other parts. For models with electronic climate control the steps are to disconnect the battery, remove the lower glove box panel, and blower motor housing parts, clean and reinstall the blower motor. In the 850 and C70/S70/V70 Series, disconnect the battery, remove the soundproofing panels, glove compartment and fan motor and install the new fan motor and components in reverse order, reconnect the battery, and test the function of the fan motor.
