How do you remove and replace the air conditioning pressure cycling switch and high-pressure cut-off switch on Ford F-150?

Both switches are threaded onto Schrader valves, so discharging the air conditioning system is unnecessary for their removal. The pressure cycling switch detects low refrigerant line pressure at 21 to 23 psi, turning the A/C compressor off and back on again at 42 psi. If pressure exceeds 435 to 475 psi, the A/C Compressor Cut-Out Switches will deactivate the A/C compressor. To remove the switch, unplug the electrical connector and use an open-end wrench to detach the air conditioning pressure cycling switch from the accumulator fitting. The A/C Compressor Cut-Out Switches are removed in the same manner, as it is mounted to a high-pressure A/C line. Next, unscrew the switch from the Schrader valve, lubricate the switch O-ring with clean refrigerant oil of the correct type, and screw the new switch onto the threads until hand tight, then secure it. Finally, reconnect the electrical connector.

Q: How do you remove and replace the air conditioning pressure cycling switch and high-pressure cut-off switch on Ford F-150?
A: Both switches are threaded onto Schrader valves, so discharging the air conditioning system is unnecessary for their removal. The pressure cycling switch detects low refrigerant line pressure at 21 to 23 psi, turning the A/C Compressor off and back on again at 42 psi. If pressure exceeds 435 to 475 psi, the A/C Compressor Cut-Out Switches will deactivate the A/C compressor. To remove the switch, unplug the electrical connector and use an open-end wrench to detach the air conditioning pressure cycling switch from the accumulator fitting. The A/C Compressor Cut-Out Switches are removed in the same manner, as it is mounted to a high-pressure A/C line. Next, unscrew the switch from the Schrader valve, lubricate the switch O-ring with clean refrigerant oil of the correct type, and screw the new switch onto the threads until hand tight, then secure it. Finally, reconnect the electrical connector.
