Four Seasons HVAC Cut-Off Switch P/N:35866
Help guard your A/C compressor against excessive system pressure with the Four Seasons HVAC Cut-Off Switch / High Cut-Out Pressure Switch 20053, a direct-fit replacement for the 2003-2006 Ford Expedition, 2003-2006 Lincoln Navigator and 2003-2005 Lincoln Aviator. This system-mounted switch is listed under both names. It monitors refrigerant pressure on the high side of the A/C system and is designed to interrupt compressor operation if that pressure climbs past its limit.
Four Seasons brings more than 50 years of mobile A/C experience to engineering and testing its components, and this Four Seasons switch is part of that vehicle-specific lineup. If the compressor won't engage, cycles off unexpectedly, or the vents blow warm air, a failed HVAC cut-off / high cut-out pressure switch may be one cause. These symptoms can also come from other parts of the system, so diagnose the cause before replacing the switch. Consult the vehicle service information for the correct installation procedure and refrigerant handling requirements.
