B2562 Lincoln Code - Auxiliary Blower Motor Speed Relay 1 Circuit Open/Short To Ground
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 1, Auxiliary Blower Motor Speed Relay 1 harness is open or shorted, Auxiliary Blower Motor Speed Relay 1 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 B2562 Lincoln Description
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.
