I am fixing my air conditioning on my TR. The air conditioning was not working when I bought the car a year ago. So I purchased all the necessary components including the main refrigerent line that runs along the top of the radiator. There are two fittings on the line. One is by the passenger side of the radiator and I know that this fitting is the high side service port. The other fitting is located by the compressor but I do not know what its called/ I have the old refrgigerent line but the sensor that connects to it is broke. I tried looking at the scematic but it does not show what the sensor is or what its for. If anybody could help me out it would be greatly appreciated. Thanks.
I figured out that the sensor is for the high-low operation of the radiator fan but does anybody have the GM part number for it? Thanks
GM number for rad fan high low relay is 25526984

The sensor is not a relay rather it is a switch that activates the relay. I finally located it on an electrical diagram. It is called an a/c high pressure switch. Thanks for the help Phil. Do you by any chance have the part number to this switch. I called the Buick dealership they will give me a price($62) but not a part number. Probably because they know I will try to cross reference the number at the auto parts store which is exactly what I intend to do. Thanks in advance to anybody who can help.
GM number for sensor in A/C line behind compressor is # 25527510
