Four Seasons 37326 A/C Clutch Cycle Switch
Temperature-Controlled A/C Clutch Cycling
The Four Seasons 37326 Temperature Switch is a system-mount A/C clutch cycle switch built for electronic activation in 12-volt HVAC systems. It uses a rectangular connector, 3 terminals, and a cycling style to help regulate compressor clutch operation based on temperature thresholds.
Four Seasons Temperature Switch line components are built for direct HVAC service applications where accurate temperature-based cycling is needed. This Four Seasons 37326 part meets or exceeds OEM requirements and is made with a plastic housing in a red finish.
Key Features
- Part number 37326 A/C clutch cycle switch for temperature-based compressor control
- Electronic activation control with 12-volt operation
- 3-terminal rectangular connector for system-mount installation
- Cycling style switch with 32 degrees off and 38 degrees on settings
- Plastic construction with red housing
- Meets or exceeds OEM specifications
Detailed Product Description
This temperature switch is used in HVAC systems that cycle the A/C compressor clutch according to temperature changes. It is a direct-fit service part for Nissan Frontier, Nissan Xterra, Nissan Altima, Nissan Sentra, and Nissan 200SX applications listed below. The Four Seasons 37326 is a practical replacement when the original A/C clutch cycle switch no longer responds correctly to temperature input or system cycling demands.
