Check continuity at high and low pressure switches during cycle..

I see one pressure switch it has 3 wires,that the only one?

I have never looked for them on my car but I would assume there are 2 switches. Low pressure switch on suction line (large line) and high pressure switch on liquid line (small line). Suction would be the most likely culprit,(if the malfuntion is a switch) if compressor cycles on immediately then shuts off it's a sign of low refrigerant.

It does not cycle at all. Does the digital control in the dash ever go bad? To make the conpressor not come on?
