Refrigerant Pressure Sensor / Switch: Service and Repair
Pressure Cycling Switch
IMPORTANT NOTE !
Early models do not have a Schrader type valve and system must be discharged before replacing. Due to the orifice tube being relocated, the previous
high pressure port located on the liquid line is now on the low pressure side of tube. Early-build vehicles do not have a high pressure port located on the
accumulator hose assembly.
1.
Disconnect battery ground cable, then disconnect switch lead.
2.
Unscrew and remove switch unit. It is not necessary to discharge system refrigerant during this procedure, as switch unit is mounted on a
Schrader valve.
3.
Reverse procedure to install.
