MOTOKU A/C Pressure Clutch Cycle Sensor for Chevy & GMC — Direct OEM Fit, Restores Compressor Control (1996–2016)

This sensor is designed to fit a broad range of General Motors vehicles from the late 1990s through the 2010s, offering a cost-effective replacement for worn or faulty A/C pressure switches. It restores the electrical feedback the compressor clutch needs to engage or disengage based on refrigerant pressure, helping the air-conditioning system operate safely and reliably when installed correctly.

Which vehicles does this MOTOKU A/C clutch cycle sensor fit?

This switch is compatible with many GM platforms across Chevrolet, GMC, Cadillac, Buick, Oldsmobile and Hummer lineups. Fitment spans trucks, SUVs, vans and luxury SUVs produced between the late 1990s and mid-2010s; review your vehicle year and model against the list below to confirm compatibility.

• Cadillac Escalade (1999–2009), Escalade EXT (2003–2007), Escalade ESV (2004–2008)
• Chevrolet Silverado, Tahoe, Suburban, Avalanche, Trailblazer, Express, Astro and more (various years 1996–2016)
• GMC Sierra, Yukon, Savana, Envoy and Safari models (various years 1999–2015)
• Buick Rainier (2004), Oldsmobile Bravada (2002), Hummer H2 (2004)

How does this pressure switch replace factory part numbers?

The MOTOKU sensor is manufactured to match the electrical characteristics and mounting style of several OEM switches, making it a direct replacement for multiple part numbers. Using an equivalent sensor avoids the need for unique programming or additional adaptors on compatible models.

• Directly replaces OEM references like 12209861, 1711456 and 37308
• Also cross-references 9510082, TL850-8707, 15035084, 15144494, 52476843
• Designed to match connector fitment and pressure-response behavior of original units

What symptoms indicate the A/C clutch cycle sensor needs replacement?

Common signs include intermittent compressor engagement, A/C that stops cooling under certain conditions, or a blower that behaves erratically when the compressor cycles. If diagnostics point to incorrect pressure readings or an open/shorted switch, replacing the sensor is a typical next step.

• Compressor clutch fails to engage or cycles rapidly
• Air conditioning cooling is inconsistent or weak
• Diagnostic trouble codes or bench testing show a faulty pressure switch

What should I know about installation and compatibility checks?

Installation typically requires basic hand tools and disconnecting the battery before swapping the sensor to avoid electrical shorts. Verify the vehicle year, model and engine/A/C configuration against the compatibility list, and compare the connector and thread type to the original switch.

• Disconnect battery and relieve system pressure only if performing refrigerant work with a certified technician
• Confirm connector pinout and thread size match the original sensor before installation
• After installation, test system operation and clear any stored codes as needed

Who is this for: Technicians, DIY mechanics and fleet managers seeking a reliable, aftermarket pressure switch compatible with a wide range of GM vehicles. If you need a direct-fit replacement for worn or faulty A/C pressure switches across Chevrolet, GMC, Cadillac, Buick, Oldsmobile or Hummer models listed above, the MOTOKU A/C clutch cycle sensor provides a cost-conscious and straightforward option for restoring compressor control and system responsiveness.
