Pressure Switch Test
- Pressure switch is located near receiver-drier. See Fig 1. Install manifold gauge set. Turn ignition on. Start engine. Turn blower andA/C on. Observe system pressure. Unplug pressure switch connector. Check continuity between pressure switch terminals No. 1 and 4.
- Continuity should not exist if high side pressure is less than 28 psi (2.0 kg/cm2
) or greater than 455 psi (32 kg/cm2
). Continuity should exist if high side pressure is 28-455 psi (2.0-32 kg/cm2
). If continuity is not as specified, replace pressure switch.
