  Q: How to replace the accumulator/drier in an air conditioning system on Nissan Quest?

  A: The accumulator/drier stores refrigerant and removes moisture from the system. When any major air conditioning component is replaced, or the system has been apart and exposed to air for any length of time, the accumulator/drier must be replaced. Take the vehicle to a dealer service department or automotive air conditioning shop and have the air conditioning system discharged and the refrigerant recovered. Disconnect the cable at the negative battery terminal. Disconnect the electrical connector at the compressor clutch cycling switch on top of the accumulator/drier. If the accumulator/drier is to be replaced with a new one, remove the cycling switch to transfer to the new drier. Disconnect the refrigerant inlet and outlet lines. The outlet line is disconnected at the firewall. Use spring-lock coupling tools to disconnect the two lines. To disconnect a fitting, close the two halves of the tool over the connection and push the tool towards the garter spring. This expands the spring to release its hold. While the spring is expanded and tool is still in place, pull in opposite directions on the two lines to separate the connection. Cap or plug the open lines immediately. Loosen the clamp-bolt on the mounting bracket and slide the accumulator/drier assembly up and out of the mounting bracket. If you are replacing the accumulator/drier, add two ounces of clean refrigerant oil to the new accumulator. This will maintain the correct oil level in the system after the repairs are completed. Place the new accumulator/drier into position, tighten the mounting bracket bolt lightly, still allowing the accumulator drier to be turned to align the line connections. Install the inlet and outlet lines. Lubricate the 0-rings using clean refrigerant oil and reconnect the lines. Now tighten the clamp bolt securely and reconnect the electrical connector. Connect the cable to the negative terminal of the battery. Have the system evacuated, recharged and leak tested by a dealer service department or an air conditioning repair facility.
