Four Seasons HVAC Binary Switch P/N:35993

Keep your A/C compressor responding to refrigerant pressure the way the system intends with the Four Seasons 35993 HVAC Binary Switch, a system-mounted binary pressure switch. It fits many Honda and Acura vehicles, among them the 1997-2001 Honda CR-V, 1994-2007 Honda Accord and 1994-2005 Honda Civic. See the Buyer's Guide tab for the full list of applications and engine details.

A binary pressure switch watches refrigerant pressure in the air-conditioning system. It is designed to open the compressor clutch circuit when pressure falls too low or climbs too high, which helps protect the compressor from running outside its safe range.

• Engineered and tested: Four Seasons designs and tests its products for years of trouble-free operation. The company has more than 50 years of mobile A/C experience.
• Vehicle-specific design: Built for the listed vehicle applications.
• Sealing parts included: Comes with the gaskets, O-rings or seals needed to replace the switch properly.
• Zinc coated and color coded: The zinc coating resists corrosion, and the color coding makes the switch easy to identify.

Signs this part may need replacing include an A/C compressor that won't engage, cycles erratically or cuts out, and air from the vents that doesn't stay cold. Low refrigerant and electrical faults can cause the same symptoms, so diagnose the system before replacing the switch.
