Code B1260 GMC Description
The B1260 GMC code indicates a problem with the solar radiation sensor circuit, specifically a short to the battery. The solar radiation sensor is a component of the vehicle's climate control system that measures the intensity of sunlight and adjusts the interior temperature accordingly. When this sensor circuit is shorted to the battery, it can cause inaccurate readings or a complete malfunction of the sensor, leading to issues with the climate control system.
Common Causes of B1260 GMC
- Short circuit in the wiring connecting the solar radiation sensor to the battery.
- Faulty solar radiation sensor.
- Malfunctioning control module that interprets sensor readings.
- Corrosion or damage to the sensor circuit components.
- Electrical issues within the climate control system.
Symptoms of B1260 GMC
- Inaccurate temperature adjustments by the climate control system.
- Climate control system not responding to changes in sunlight intensity.
- Automatic headlights not functioning correctly.
- Sunroof not adjusting properly based on sunlight.
How to Fix B1260 GMC
- Begin by diagnosing the exact cause of the short to the battery in the solar radiation sensor circuit using a multimeter and wiring diagrams.
- Inspect the wiring harness for any visible damage or signs of a short circuit. Repair or replace any damaged wiring as needed.
- Test the solar radiation sensor itself to determine if it is functioning correctly. Replace the sensor if it is found to be faulty.
- Check the control module that interprets the sensor readings for any malfunctions. Replace the control module if necessary.
- Clear the diagnostic trouble codes from the vehicle's memory and test the climate control system to ensure proper operation.
Cost to Fix B1260 GMC
The typical repair costs for addressing a B1260 GMC code can vary depending on the specific cause of the issue. In general, replacing a faulty solar radiation sensor or repairing a wiring harness can cost between $150 to $300, including parts and labor. If the control module needs to be replaced, the cost can range from $200 to $500. It's important to note that the actual cost of repairs can be influenced by factors such as the vehicle make and model, the location of the repair shop, and the extent of the damage.
