    Q:
    How to replace the A/C Compressor Cut-Out Switches on Buick Rainier? Posted by Customer
    A:
    To change the air conditioning (A/C) low pressure switch, first, the halogen leak detector (J39400-A) is used to leak test the fittings of the components after making the installation. Start with disconnecting the a/c low pressure switch electrical connector, and then remove the a/c low pressure switch from the accumulator. Remove the a/c low pressure switch port o-ring seal from the accumulator and put an o-ring seal at the appropriate place. Then, install ac low pressure switch to the accumulator and secure it with 4.8 n.m (42 lb in). Finally, replace the a/c low pressure switch electrical connector.

    How to Replace A/C Compressor Cut-Out Switches for Low Pressure Sensor on Cadillac Escalade EXT? Posted by Customer
    A:
    Begin the switch replacement by unplugging the electrical connector from the a/c low pressure switch while removing the switch from the accumulator and disposing of the o-ring. Fasten the a/c low pressure switch to the accumulator by applying 6 n.m (53 lb in) torque following the service precautions notice for fasteners. The kit j 39400-a should be used now to perform a leak test before you reconnect the electrical connector to the a/c low pressure switch.
