A/C Leak Present for Toyota
Some 2011-2013 Toyota Highlander, Sequoia and Sienna vehicles may exhibit a condition where there is a lack of cooling from the air conditioning system. An A/C line retainer (piping clamp) may have become unlatched and caused a refrigerant leak.
Recover the refrigerant. If the A/C line retainer is still present but unlatched, remove it and replace it with a new A/C line retainer. Recharge the system and verify operation.
