Have the air conditioning system discharged and disconnect the negative battery cable. Disconnect the compressor clutch wiring harness and remove the drivebelt. On 2012 and later models, also disconnect the wiring harness to the Powertrain Control Module (PCM) and move it out of the way. Disconnect the refrigerant lines from the rear of the compressor and plug the open fittings. Unbolt the compressor from the mounting brackets and lift it out of the vehicle. If a new compressor is being installed, follow the directions regarding the draining of excess oil prior to installation. The clutch may need to be transferred from the original to the new compressor. Replace all O-rings with new ones made for air conditioning system use and lubricate them with refrigerant oil. Have the system evacuated, recharged, and leak tested by the shop that discharged it.
