Detailed Product Description

The Four Seasons 35833 is a pressure-actuated HVAC switch used in automotive air conditioning systems where low-pressure cut-out control is required. Its open compressor state and system-mounted configuration make it suitable for pressure monitoring in HVAC circuits that rely on a direct electrical response from the refrigerant system. If you are replacing a failed HVAC pressure switch on a vehicle such as a Ford F-150 or Chevrolet Silverado, this part number is commonly searched as a direct replacement reference for pressure switch service.

This Four Seasons pressure switch uses a wire lead connector and a female threaded fitting to integrate with the HVAC system. The part is built from plastic and metal and is specified as an OEM-level replacement. This part cross-references UAC SW9061C and SW11415C for the same application.

What This Part Helps Address

• HVAC compressor cut-out caused by low refrigerant pressure
• Intermittent A/C operation tied to pressure switch failure
• Electrical signal loss at the HVAC pressure control point
• Incorrect compressor cycling from a worn pressure switch
• Service replacement needs for a system-mounted low cut-out switch

Installation Notes and Tips

Verify the fitting thread size, connector style, and switch type before installation. The Four Seasons 35833 uses a wire lead connector and a 7/16 in. x 20 female fitting, so matching the original HVAC connection is important for proper fitment. Confirm the vehicle’s pressure switch location and compare the original part number before replacing the component. For fitment-based searches, this part is commonly referenced for Ford F-150 and Chevrolet Silverado HVAC pressure switch service, but final application should always be matched to the vehicle’s original specification.
