Disconnect the negative battery cable, tag and disconnect the electrical harnesses from the blower motor, and if the vehicle is equipped with a plastic splash shield, remove it from the right side of the cowl. Remove the blower motor attaching screws and the motor. The installation is the reverse of removal.

Remove the battery cable from the negative terminal. Disconnect the electrical connections from the blower motor. Take out all screws that hold in place the blower motor and separate it from the case. The process of installing is simply opposite to removing.

Disconnect the cable from the negative battery terminal, ensuring that on models equipped with the Delco LoC II audio system, the lockout feature is turned off before disconnecting the battery. In the engine compartment, remove the plastic firewall covers by taking out the central screw and lifting them off. Disconnect the wires from the blower motor by detaching the wiring harness clip and removing the mounting screws around the perimeter of the blower. Detach the blower motor cooling tube and then remove the blower motor mounting bolts to separate the motor/fan assembly from the housing; on V6 engines, it may be necessary to remove the alternator for better access. Remove the retaining nut and slide the blower off the motor shaft by taking off the nut and slipping the fan off the motor shaft. Installation is the reverse of the removal procedure.

Disconnect the battery ground cable, then remove all wiring, hoses, etc. to the right-hand fender skirt. On 1977 and later models, the assembly is accessible from under the hood. Simply disconnect the blower lead wire at the motor and remove the blower-to-case attaching screws. Raise the vehicle. Remove all fender skirt attaching bolts except those fastened to the radiator support. Pull outwards, then down on the fender skirt and place a 2 x 4 inch wooden block between the skirt and fender. Remove the blower wheel retaining nut and separate the wheel from the blower. Pass the blower through the fender skirt opening. Installation is the reverse of the removal procedure, but ensure that the blower wheel is fitted with the open end away from the motor. Disconnect the battery ground cable. Drain the radiator. Disconnect the heater hoses at the core connections. Temporarily plug the core tubes to prevent coolant spillage. Remove the nuts from the heater distributor studs on the engine side of the dash panel (firewall). Remove the glovebox and door assembly. Using a 1-inch drill, drill out the lower right-hand distributor stud from beneath the dash. Pull the distributor assembly from the dash panel mounting, taking care not to kink the bowden cables. When clearance is obtained, disconnect the bowden cables and resistor wires, and remove the distributor assembly from the vehicle. Remove the core assembly from the distributor assembly. When installing, reverse the removal procedure, ensuring that the hose from the water pump goes to the top heater core pipe. Ensure that the case sealer is intact before fitting the core; if necessary, fit a new sealer. Replace the drilled-out stud with a new screw and pal (stamped) nut. After filling the cooling system, run the engine and check for coolant leaks. Disconnect the battery ground cable. Remove the ashtray assembly. Remove the six steering column trim panel screws and lower the panel and control as an assembly. Disconnect all cables and wires at the control head. Remove control head attaching screws and remove control head. Installation is a reversal of removal; however, make sure of cable operation before completing assembly.

The front blower motor is on the right side of the dash. For removal, disconnect the battery's negative cable. Disconnect blower wiring and hose. Remove the glove box and right kick panel. On older models, disconnect the ECM wiring and remove a bolt from the instrument panel. For 1988-1991 models, unscrew the fan nut. For 1992 onwards, remove the motor shaft tip and detach the fan using a puller. On Suburban models, disconnect the battery, remove the rear trim panel, and unplug blower motor wiring. Then, remove the blower motor. Installation is the reverse process.

To remove the blower motor and inlet assembly on 1974-1977 models, remove the right front inner fender panel and disconnect the wiring at the lower assembly. Remove the nuts and screws securing the inlet assembly to the dash panel and separate the blower motor from the inlet assembly. For the air distribution duct and core, locate the heater core within the heater case under the dashboard. Disconnect the battery, drain the radiator and heater hoses, and remove the heater case attaching nuts and screws. Remove the entire case assembly from the dash panel and the core from within the case. To remove the A/C switch assembly, disconnect the negative battery cable, remove the screws from the steering column trim cover, and remove the knobs from the heater control and radio. Remove the screws from the front of the control panel and pull the control panel assembly from the instrument panel. For 1978-1980 models, remove the glove box and disconnect the electrical connectors at the blower motor to remove the blower assembly. To remove the heater core, disconnect the negative battery cable, drain the cooling system, disconnect the heater hoses and the electrical connectors at the blower motor, and remove the front module cover screws. Remove the heater core from inside the heater module.

Remove the battery cable from the negative terminal. Disconnect the electrical connections from the blower motor. Take out all screws that hold in place the blower motor and separate it from the case. The process of installing is simply opposite to removing.
