WARNING: This page is about a different car, the 2001 Suzuki Vitara, 2001 Suzuki Grand Vitara, 2000 Suzuki Vitara, and 2000 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
The dual-pressure switch is mounted in top of receiver-drier, and acts as an A/C system circuit breaker. The switch stops compressor operation by turning off A/C compressor circuit when refrigerant pressure drops to less than or exceeds a specified range.
