REMOVAL & INSTALLATION
See Figure 1
The cycling switch is mounted on a Schrader-type fitting on the suction side of the Accumulator/Drier.
This procedure requires the evacuating and recharging of the A/C refrigerant. An approved recycling/recovery machine is needed to do this. If you do not have the proper certification in addition to the necessary equipment, you must consult a certified professional to evacuate the system before you start the procedure, and recharge the system when the job is complete.
- Determine whether your particular A/C system uses R-12 or R-134a refrigerant. Most vehicles have identification stickers placed in the engine compartment and on certain components of the A/C system to alert you to which type of refrigerant is used.
- Have the A/C refrigerant properly evacuated using an approved recovery/recycling machine.
- Disconnect the negative battery cable.
- Unfasten the wire harness attached to the cycling switch.
- Using an open-ended wrench or equivalent, loosen and remove the cycling switch from the accumulator. Remove and discard the O-ring.
- Install a new O-ring coated with refrigerant oil on to the accumulator nipple.
- Screw the cycling switch on to the accumulator nipple. Hand-tighten the switch.
- Fasten the harness to the cycling switch.
- Connect the negative battery cable.
- Charge the A/C using an approved recovery/recycling machine.
- Run the A/C system and check to make sure it functions correctly.
