- Q:How can the pressure cycling switch be replaced for the 2002 Mercury Mountaineer? Posted by Customer
- A:To replace the switch, first unplug the electrical connector from the switch. Then, unscrew the switch from the Schrader valve. Since both switches are threaded onto Schrader valves, it isn't necessary to discharge the air conditioning system. Next, lubricate the switch O-ring with clean refrigerant oil of the correct type. Screw the new switch onto the threads until hand tight, then tighten it securely. Finally, reconnect the electrical connector.Posted by FordPartsGiant Specialist
