What is a B2559 Aux A/C Blower Motor Relay Circuit Short to Battery Issue?

A B2559 Aux A/C Blower Motor Relay Circuit Short to Battery issue is a problem that occurs when there is a short circuit in the blower motor relay circuit. This can cause the blower motor to stop working, which can result in a lack of cool air coming from your car’s air conditioning system. This issue can be caused by a variety of factors, including a faulty blower motor relay, damaged wiring, or a malfunctioning blower motor.

Diagnosing the Issue

To diagnose a B2559 Aux A/C Blower Motor Relay Circuit Short to Battery issue, you’ll need to perform a few tests. Here’s what you’ll need to do:

Step 1: Check the Blower Motor Relay

The first step in diagnosing the issue is to check the blower motor relay. To do this, you’ll need to locate the relay and remove it from its socket. Once you’ve removed the relay, use a multimeter to test the resistance between the relay’s terminals. If the resistance is within the manufacturer’s specifications, the relay is likely not the issue.

Step 2: Check the Wiring

If the blower motor relay is not the issue, the next step is to check the wiring. Start by inspecting the wiring for any visible damage or wear. If you notice any damage, you’ll need to repair or replace the damaged wiring. If the wiring appears to be in good condition, use a multimeter to test the resistance between the wiring and the blower motor relay. If the resistance is within the manufacturer’s specifications, the wiring is likely not the issue.

Step 3: Check the Blower Motor

If the blower motor relay and wiring are not the issue, the next step is to check the blower motor. Start by disconnecting the blower motor from its wiring harness. Once you’ve disconnected the blower motor, use a multimeter to test the resistance between the blower motor’s terminals. If the resistance is within the manufacturer’s specifications, the blower motor is likely not the issue.

Solving the Issue

Once you’ve diagnosed the issue, it’s time to solve it. Here’s what you’ll need to do:

Step 1: Replace the Blower Motor Relay

If the blower motor relay is the issue, you’ll need to replace it. Start by purchasing a new blower motor relay that is compatible with your car’s make and model. Once you have the new relay, install it in the socket where the old relay was located.

Step 2: Repair or Replace the Wiring

If the wiring is the issue, you’ll need to repair or replace the damaged wiring. Start by identifying the damaged wiring and determining whether it can be repaired or needs to be replaced. If the wiring can be repaired, use electrical tape or wire connectors to fix the damage. If the wiring needs to be replaced, purchase new wiring that is compatible with your car’s make and model and install it.

Step 3: Replace the Blower Motor

If the blower motor is the issue, you’ll need to replace it. Start by purchasing a new blower motor that is compatible with your car’s make and model. Once you have the new blower motor, install it in the location where the old blower motor was located.
