B2563 Ford Code - Auxiliary Blower Motor Speed Relay 2 Circuit Short To Voltage

Quick Answer

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). Common causes include Faulty Auxiliary Blower Motor Speed Relay 2, Auxiliary Blower Motor Speed Relay 2 harness is open or shorted, Auxiliary Blower Motor Speed Relay 2 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2563 Ford Description

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.
