AC Not Cold with Bad Odor
The air conditioning system is not producing cold air and emits a foul smell. This typically indicates a refrigerant issue, a failing compressor, or microbial growth in the evaporator.
Diagnosis Details
Possible Causes
Low refrigerant charge due to a leak in the system (common in Jeep Wranglers, especially at seals or condenser).
Faulty AC compressor or clutch not engaging, preventing refrigerant circulation.
Mold or mildew buildup in the evaporator core causing bad odor and reduced cooling efficiency.
Blocked or dirty cabin air filter restricting airflow and contributing to odor.
