AC Not Cold, Bad Smell, Won't Turn On
The AC system is not producing cold air, emits a bad smell, and the blower does not activate. This suggests an electrical or mechanical failure in the AC system, possibly due to a faulty blower motor, resistor, or refrigerant leak with mold growth.
Diagnosis Details
Possible Causes
Blower motor resistor failure or blower motor seized, preventing fan operation and causing electrical smell.
Refrigerant leak combined with mold/bacteria buildup in evaporator, causing bad smell and no cooling.
Faulty AC compressor clutch or relay, or blown fuse, preventing system from engaging.
