Help protect your A/C compressor from running on low refrigerant pressure with the Four Seasons HVAC Cut-Off Switch, part number 20890. It is a system-mounted low cut-out pressure switch and a direct-fit replacement switch for the 1985-1996 Jaguar XJS. See the "Vehicles it fits" section for engine details.
A low cut-out pressure switch monitors refrigerant pressure in the A/C system. When that pressure drops too low, the switch interrupts compressor operation so the compressor does not run without enough refrigerant. Four Seasons engineers and tests its parts and draws on more than 50 years of mobile A/C experience.
- Corrosion resistance: Zinc coated to help resist corrosion.
- Vehicle-specific: Built for specific vehicle applications.
- Sealing parts included: Supplied with the gaskets, O-rings or seals needed to replace the switch properly.
- Color coded: Makes the switch easy to identify.
Signs this part may need replacing: The A/C compressor won't engage, it cycles on and off abnormally, or the system blows warm air. A low refrigerant charge and other faults can cause the same symptoms, so diagnose the system before you replace the switch.

Frequently Asked Questions
Will this Four Seasons switch fit my 1985-1996 Jaguar XJS?
It is listed as a direct-fit replacement for the 1985-1996 Jaguar XJS. The "Vehicles it fits" section has the engine details for your car.
What does a low cut-out pressure switch do?
It monitors refrigerant pressure in the A/C system. When pressure falls too low, it interrupts compressor operation so the compressor does not run without enough refrigerant.
What comes in the box with part 20890?
The switch comes with the gaskets, O-rings or seals needed to replace it properly.
How is the switch protected against corrosion?
It has a zinc coating to help resist corrosion. It is also color coded so it is easy to identify.
What should I know before installing it?
Diagnose the A/C system first, because low refrigerant can cause the same symptoms. Follow the vehicle service information, including any refrigerant-handling steps, and install the supplied seals.
