Problem overview

Some Chevrolet Trax owners report experiencing issues with their air conditioning not blowing cold air, often accompanied by a check engine light due to a faulty thermostat assembly. Common problems leading to inadequate cooling include refrigerant leaks, electrical climate control issues, or malfunctioning air conditioning compressors. Many owners find that low refrigerant levels, along with dirty evaporator or condenser components, contribute to the AC not performing effectively. Other factors such as a dirty cabin air filter, clogged condenser or evaporator, faulty blower motor, or electrical system issues can also hinder the AC's operation. Insufficient refrigerant due to leaks, particularly if the system has not been recharged for an extended period, is frequently cited as a cause for the AC's failure to blow cold air. It is recommended that owners consult a qualified mechanic to diagnose and address any underlying issues, including the potential need to repair or replace the faulty thermostat assembly.
