    Q:
    How to replace the HVAC Pressure Switch on Pontiac G6? Posted by Barbie H.
    A:
    When it comes to the HVAC Pressure Switch, it is threaded onto a Schrader valve and this shows that there is no need for discharging the air conditioning system so as to replace it. Nonetheless, if either extreme occurs, this sensor will protect the system from running. To modify it, unplug the electrical connector from the sensor first. Next, unscrew the sensor from the Schrader valve using a back-up wrench on the fitting for the sensor to avoid damaging the refrigerant line. Then lubricate switch 0-ring with clean refrigerant oil of correct type. After screwing on new sensor threads until hand tight and then tighten securely. Finally, reconnect electrical connector.
