Toyota Not Cool With A/C Issue
Some 2011-2013 Toyota Highlander, Sequoia and Sienna vehicles may exhibit a condition where there is a lack of cooling from the air conditioning (A/C) system. An A/C line retainer (piping clamp) may have become unlatched and caused a refrigerant leak.
If the A/C line retainer is still present but unlatched, remove it and replace it with a new retainer. If missing, obviously replace it. Recharge the system, as needed.
