What NHTSA recorded
Vehicle description: school buses. Some heater/defroster units were built with the blower motor wired improperly. When wired improperly the blower motor runs backward and airflow for heating and defrosting is very limited. This does not meet the requirements of fmvss no. 103, "windshield defrosting and defogging systems."
Possible consequence
Defrosting needs may not be achieved and could restrict driver visibility, increasing the risk of a crash.
Remedy
Owners will be instructed on how to inspect and repair the defect by switching the connection of two wires.
