GPD 1815258 HVAC A/C Refrigerant Pressure Switch

The GPD 1815258 is an OE-replacement HVAC A/C refrigerant pressure switch designed to restore proper air conditioning system operation. GPD (Global Parts Distributors) is a leading national brand of aftermarket automotive air conditioning components, offering one of the most complete A/C and heat exchange programs in the market.

The A/C pressure switch is a critical safety and control component in the vehicle's air conditioning system. It monitors refrigerant pressure and provides feedback to the engine control module (ECM) or engine management system. On modern vehicles, the ECM uses this signal to regulate compressor operation, while on earlier platforms the switch works to directly cut compressor power when pressures fall outside of safe operating ranges — protecting the compressor from damage due to low refrigerant or excessive head pressure.

Key Features:

• Direct-fit OE-style replacement for precise installation
• Engineered to match original equipment specifications and performance
• Monitors refrigerant pressure to protect the A/C compressor from damage
• Provides critical feedback to the ECM for proper A/C system control
• Built and tested to meet GPD's stringent quality and durability standards
