  Q: How to remove and install the A/C Switch and Blower Motor on Chevrolet Nova?

  A:

  To replace the blower motor, first disconnect the battery ground cable and remove all wiring and hoses from the right-hand fender skirt. Raise the vehicle securely on jackstands, then remove the eight rearmost fender skirt-to-fender attaching screws. Pull the fender skirt outwards and down, placing a 2 x 4 inch wooden block between the skirt and fender. Next, remove the blower motor mounting screws and pass the blower through the fender skirt opening. Detach the blower wheel by removing the retaining nut. For installation, reverse the removal steps and apply a bead of body putty around the blower motor flange for a good seal. To work on the air distribution duct and heater core, disconnect the battery ground cable and drain the radiator if necessary. Disconnect the heater hoses at the core connections, plugging the core tubes to prevent coolant spillage. Remove the nuts from the heater distributor studs on the engine side of the firewall, then take out the glove box and door assembly. Drill out the lower right-hand air distribution stud from beneath the dash, then pull the heater case/distribution assembly from the dash panel, being careful not to kink the control cables. Disconnect the cables and resistor wires before removing the distribution assembly. Take out the heater core from the distribution assembly, and during installation, ensure the hose from the water pump connects to the top heater core pipe, checking that the case seal is intact and applying a new seal if necessary. Replace the drilled-out stud with a new screw and stamped nut, then fill the cooling system and check for leaks after running the engine. For the control head assembly, disconnect the battery ground cable, remove the radio if applicable, and take out the control head to panel instrument screws to lower the control assembly. Detach the control cables and wires, then remove the control head, ensuring to detach the control cable(s) from the heater control panel. Installation follows the reverse of the removal process.
