GM GENUINE PARTS A/C Clutch Cycling Switch 15-2962 (52466358) OEM replacement — evaporator temp & pressure protection

This GM Genuine Parts cycling switch is an original-equipment replacement designed and validated by GM engineers for compatible Chevrolet, Buick, GMC, and Cadillac vehicles. It senses evaporator temperature and pressure and interrupts or restores power to the compressor clutch coil to prevent excessively low pressure or temperature. The unit meets the manufacturing and testing standards expected of factory-installed components and may formerly have appeared under ACDelco GM Original Equipment (OE).

How does this switch protect my vehicle’s air conditioning?

The switch continuously monitors evaporator conditions and cuts power to the compressor clutch when pressure or temperature drops below safe thresholds, preventing compressor damage and potential refrigerant issues. When conditions return to acceptable levels it restores clutch operation so the A/C can resume cooling.

• Monitors evaporator temperature and pressure to prevent low-pressure operation
• Interrupts compressor clutch field coil to stop compressor engagement
• Automatically restores clutch when conditions normalize

Will this part fit my GM vehicle and maintain OE performance?

This part is vehicle-specific and engineered to the same design and validation standards used by GM for production fitment. Using a GM Genuine Parts switch helps maintain original-system behavior and compatibility with factory safety and control systems.

• Designed and validated by GM engineers for exact fitment on specified models
• Maintains original control characteristics with the vehicle’s A/C circuitry
• Matches OE materials and testing benchmarks for reliable service

What symptoms indicate the clutch cycling switch needs replacement?

Signs of a failing cycling switch include the compressor not engaging, erratic compressor cycling, or the system shutting down to avoid low-pressure operation. Diagnosing with proper A/C pressure and temperature checks confirms whether the switch or another component is at fault.

• Compressor fails to engage despite correct electrical supply
• Rapid on/off cycling of the compressor clutch during operation
• A/C system shutting down during normal running to protect compressor

How do I ensure a reliable replacement and installation?

Choose the GM Genuine Parts 15-2962 (52466358) switch to ensure OEM compatibility and quality. Installation should follow vehicle-specific service procedures, including system evacuation and leak checks where applicable, or be installed by a qualified technician.

• Select the exact part number for your vehicle application
• Follow manufacturer torque and wiring instructions during installation
• Perform pressure checks and leak testing after replacement
