First, determine if the issue is due to a clogged air filter core, replacing the air filter core can resolve it. Then check if excessive dust in the evaporator is causing the problem, requiring an air conditioning cleaning. A dirty condenser is also a reason for the air conditioning not cooling properly, simply rinsing it with a water gun during car washing can solve the issue, very simple.
