Overview:
This bulletin involves inspecting for leaves and other foreign material, cleaning,
and treating the
cooling coil and housing.
Symptom/Condition:
Some vehicle operators may experience a musty odor from the A/C system, primarily
at start
up in hot and humid climates. This odor may be the result of microbial growth
on the cooling
coil. During normal A/C system operation, condensation forms in and around the
A/C cooling
coil. When airborne pollutants mix with this condensation, bacteria and fungi
growth begins and
odor results.
Diagnosis:
If the operator describes, or the technician experiences a musty
odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.
