    Q:
    What is the role of the HVAC pressure switch in the AC system on Cadillac CTS? Posted by Customer
    A:
    The pressure cycling switch, located on top of the hard line connecting the condenser to the air conditioning thermostatic expansion valve (TXV), is crucial in the AC system. It detects low refrigerant line pressure and turns the system off and on to increase the pressure. If the pressure becomes too high, the pressure cut-off switch shuts the system off. To replace the pressure cycling switch, an automotive air conditioning technician should discharge the system first. Then, unplug the electrical connector and unscrew the old switch. Lubricate the O-ring with clean refrigerant oil before installing the new switch. Screw it in until hand tight and then securely tighten. Reconnect the electrical connector and have the technician who discharged it evacuate, recharge, and leak test the system.
