Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
Signs this part may need replacing include an A/C compressor that won't engage, a compressor that cycles on and off unexpectedly, or warm air from the vents. These symptoms can have other causes, so diagnose the system first. If a failed high cut-out switch is the cause, this switch replaces it.
