Help your A/C system keep track of refrigerant pressure with the Four Seasons switch 20995, a system-mounted HVAC pressure transducer designed to sense pressure in the A/C system and send that signal to the vehicle's controls. It fits many vehicles, among them the 2002-2006 Dodge Ram 1500, 2003-2009 Dodge Ram 2500 and 2002-2004 Jeep Grand Cherokee, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list. The part is cataloged as a switch and described by Four Seasons as a pressure transducer, so it is listed under both names.
- Zinc coated: finished with a zinc coating to resist corrosion.
- Vehicle specific: built for specific vehicle applications.
- Sealing parts included: contains the gaskets, O-rings or seals needed to properly replace the unit.
- Color coded: marked for easy identification.
Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
Signs this pressure transducer may need replacing include a compressor that won't engage, cooling that cuts in and out, or warm air from the vents. These symptoms can have other causes, so diagnose the A/C system first. If a failed transducer is the cause, the 20995 replaces it. Follow the vehicle's service procedure, which may call for refrigerant recovery.
