ACDelco 13536138 Air Conditioning Clutch Cycling Switch

The ACDelco 13536138 is a genuine GM OE air conditioning clutch cycling switch designed to maintain optimal A/C system performance. This component sensor monitors evaporator temperature and refrigerant pressure to control compressor operation and prevent system damage.

Key Features:

• Controls compressor clutch field coil engagement and disengagement
• Monitors low-side pressure to prevent evaporator freeze-up
• Protects compressor from operating under harmful low-pressure conditions
• Direct replacement for original equipment switch
• Manufactured to GM original equipment specifications for precise fit and function
• Designed for GM vehicles with factory air conditioning systems

This switch automatically cycles the A/C compressor off when refrigerant pressure drops too low, preventing compressor damage and ensuring consistent cooling performance. When proper pressure is restored, the switch re-engages the compressor clutch to resume normal operation. Essential for maintaining efficient and reliable air conditioning system function.
