ACDelco Sun Load Temperature Sensor Assembly

The ACDelco Sun Load Temperature Sensor Assembly (also called a sun load sensor, solar sensor, or sunload sensor) is part of the automatic climate control system. It measures the intensity of sunlight entering the cabin. The HVAC control module uses this reading to adjust cabin temperature, blower speed, and air distribution so the interior stays comfortable.

Key Features:

• Detects solar heat load so the automatic climate control system can compensate for direct sunlight
• Helps maintain consistent cabin temperature and passenger comfort
• Designed to match the form, fit, and function of the original equipment sensor
• Typically mounts on top of the dash for easy replacement
• Backed by ACDelco, a long-established name in genuine GM and aftermarket replacement parts

If your climate control is inconsistent, such as blowing too warm or too cold in bright sunlight, a failed sun load sensor may be the cause. Replacing it with an ACDelco sensor helps restore automatic climate control operation.
