What It Helps Address

• A/C compressor cycling caused by incorrect high-side pressure control
• Compressor shutdown needs in a high-pressure HVAC circuit
• Faulty pressure switch electrical signaling
• Loss of A/C protection from an inoperative cut-off switch
• Replacement needs for a worn or damaged system-mounted pressure switch

Installation Notes and Tips

• Verify the connector shape, terminal count, and M10 x 1.25 thread before installation.
• Confirm the vehicle uses a system-mounted high-pressure cut-off switch location.
• Inspect the harness connector and sealing surfaces for corrosion or damage before reconnecting.
• Use the vehicle service procedure to recover and recharge the A/C system as required.
• Match the pressure switch style and operating pressure to the original component specification.
