Walker Products 1017-1003 A/C HVAC Pressure Switch OE Replacement

The Walker Products 1017-1003 is an OE replacement A/C HVAC pressure switch designed to monitor refrigerant pressure levels within your vehicle's air conditioning system and communicate that data to the ECU or HVAC control module. By accurately tracking system pressure, it ensures safe and efficient compressor operation while protecting against over-pressurization and low-pressure conditions.

How It Works:

• Measures high- and low-side refrigerant pressures in the A/C system
• Converts pressure readings into an electrical signal for the ECU or climate control module
• Enables the ECU to engage or disengage the A/C compressor based on real-time pressure data
• Prevents compressor damage and maintains consistent air conditioning performance under varying load conditions

Key Features:

• Exact OE Fit: Direct replacement design for straightforward installation with no modifications required
• OE Replacement Quality: Built to meet or exceed original equipment specifications for accuracy and performance
• Durable Construction: Engineered to withstand heat, vibration, and refrigerant exposure
• Restores System Efficiency: Helps return proper compressor operation and stable cabin temperatures
• Made in USA

Common Symptoms of a Failing A/C Pressure Switch:

• A/C system not blowing cold air
• Compressor fails to engage or cycles on and off irregularly
• Fluctuating or incorrect system pressure readings
• Check Engine Light or A/C system warning light illuminated
• Reduced cooling efficiency or intermittent system performance

Backed by Walker Products' extensive experience in sensor manufacturing, the 1017-1003 delivers reliable, long-lasting performance as a direct swap for the original switch.
