Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
To diagnose the B2564 Lincoln code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
Under normal operation, ground for the blower motor is provided through the circuit from the blower motor resistor (LO and MED-LO) and the blower motor speed relay 1 (MED-HI and HI). The blower resistor is grounded through the circuit. The blower motor speed relay coils are supplied through the circuit. Blower motor speed is received by the SJB from the rear auxiliary control through the circuit. Reference voltage for the blower speed selector resistor is provided by the SJB through the circuit. The auxiliary blower motor relay coil receives ground from the Smart Junction Box (SJB) through the circuit if any blower switch position but OFF is selected.
In LO, ground for the blower motor is provided through the blower motor resistor.
In MED-LO, blower motor speed relay 2 is grounded by the SJB through the circuit. Blower motor ground circuit is connected through one half of the blower motor resistor to the circuit. The circuit is connected through the blower motor speed relay 2 to the blower motor resistor ground circuit.
In MED-HI, blower motor speed relay 1 is grounded by the SJB through the circuit. Blower motor ground circuit is connected through blower motor speed relay 2 to the circuit. The circuit is connected through one half of the blower motor resistor to the blower motor resistor ground circuit.
In HI, blower motor speed relays 1 and 2 are grounded by the SJB through the circuit. Blower motor ground circuit 515 (OG/RD) is connected through the blower motor speed relay 1 to the circuit. The circuit is connected through the blower motor speed relay 2 to the blower motor resistor ground circuit.
