I just looked - there are three switches, one on the low side (large tube) and two on the high side (small tube). The low switch is to the rear of the connector at the evaporator core. The front high side switch is called the A/C Coolant Fan Switch, and the rear high side switch is called
A/C High Pressure Cutout Switch - according to page 8A-201-4 of the FSM.
