SERVICE INFORMATION
Water entering through the fresh air intake into the blower motor may damage the blower motor. A blower case guide can be installed to divert the water. This Service Bulletin describes the installation procedure for the blower case guide.
For vehicles with air conditioning (factory-installed or AIMI air conditioning), a redesigned evaporator drain hose is also available to prevent water build-up in the evaporator.
