Four Seasons HVAC Binary Switch P/N:20975
Four Seasons 36574 switch for the 1994-1998 Mercedes-Benz SL500 and other vehicles is a binary pressure switch that mounts on the A/C system.
The switch responds to pressure in the A/C system. When it fails, you may notice warm air from the vents or a compressor that does not engage. A low refrigerant charge, a worn compressor clutch or a bad relay can be behind those signs too, so find the cause before buying a switch.
It is also a direct-fit replacement for the 1997-1998 Mercedes-Benz SL60 AMG and the 1994-1998 Mercedes-Benz SL600. If your Mercedes-Benz is a different model, year or engine, look it up on the Buyer's Guide tab.
