AC Not Cold and Bad Smell in Toyota Camry 2020
The air conditioning system is not cooling properly, especially in traffic, and there is a bad smell. This suggests a potential issue with the refrigerant level, condenser airflow, or a dirty evaporator causing odor.
Diagnosis Details
Possible Causes
Low refrigerant charge due to a small leak, causing reduced cooling at low speeds (traffic) but adequate cooling at highway speeds due to higher condenser airflow.
Clogged or dirty cabin air filter or evaporator, leading to poor airflow and musty or bad smell.
Failing condenser fan or cooling fan, which reduces heat exchange when the car is stationary or in traffic.
