Due to its location within the HVAC system, proper installation requires care to avoid damage.
Power Off: Disconnect battery negative terminal before starting work.
Drain Moisture: Ensure no standing water in HVAC case (common after rain or clogged drain tube).
Inspect Old Motor: Check for burnt windings, seized bearing, or melted connector.
Verify New Unit: Confirm impeller spins freely and wiring is intact.
Access the blower motor — usually from under the dashboard or passenger footwell.
Unplug the 2-pin electrical connector (typically red/black wires).
Remove 3–4 mounting screws securing the motor to the heater box.
Gently pull out the old motor and impeller.
Insert the new AZ1630840014(-1) unit — align shaft with impeller bore.
Reinstall screws evenly; do not overtighten.
Reconnect the power plug securely.
Restore power and test all fan speeds via dash switch.
