1994 Buick, Custom Regal 3.8 L, 90,000 mi. I believe the high-pressure switch ("limiter" switch) in the air-conditioning system that cuts the compressor out when the pressure gets too high has gone bad. I can manually get the AC clutch to work. Where can I find this switch/sensor? Thanks in advance! :)

This switch is located on the back head ( the end where the hoses are connected) of the compressor in the middle or there abouts.
