How does this switch restore A/C performance?

The pressure sensor switch monitors refrigerant pressure and signals the climate control system to engage or disengage the compressor as needed. Replacing a faulty switch often resolves intermittent compressor cycling, lack of compressor engagement, or blown fuses tied to pressure faults.

• Monitors high/low refrigerant pressure and sends electrical signal to the A/C clutch circuit.
• Direct-fit replacement avoids splicing or adapter harnesses.
