Pwede din kasi na design fault ng manufacturer. Kaya usually in later models ng toyota, made for tropical weather na talaga yung AC.
Going back, yung pagbuga ng tubig sa condenser will temporarily solve the high pressure situation since it will help the aux fan in converting gas to liquid. this process is interrupted by a weak aux fan or clogged condenser fins.
