Weak Airflow and Bad Smell from AC
The AC is not blowing cold air and has a foul odor, with consistently weak airflow. This suggests a restriction in the air path or a failing blower motor, possibly combined with a dirty cabin air filter or evaporator issues.
Diagnosis Details
Possible Causes
Clogged cabin air filter restricting airflow and causing odors from trapped moisture/debris
Blower motor resistor or blower motor failure reducing fan speed
Evaporator coil mold or debris buildup causing bad smell and reduced airflow
Refrigerant leak or compressor issue (less likely with weak airflow, but possible if system is icing up)

What You Should Do
Replace the cabin air filter first (Tesla recommends every 2 years or 20,000 miles).
If airflow remains weak, inspect the blower motor and resistor.
For the smell, use an evaporator cleaner or have the system professionally sanitized.
If AC still not cold, check refrigerant level and compressor operation.
