Chevrolet Traverse rear AC/heater blower replacement issue due to redesign requiring new housing on Chevrolet Traverse

Some Chevrolet Traverse owners report experiencing issues with the rear HVAC blower, particularly in the 2019 Traverse LT, which may not work due to a variety of factors including a blown fuse, bad relay, or malfunctioning control module. These problems can also stem from a faulty blower motor or defective climate control unit, necessitating a replacement that accommodates a redesigned housing. Additionally, some owners find that if the AC or heater fails to blow hot or cold air, it points to potential blower motor issues. Others have noted that if the vehicle is blowing coolish air, a condenser problem might be at fault. Furthermore, the AC/Heater lines running from the front to the rear HVAC can be easily damaged and must be replaced as a single unit if compromised. Accurate diagnosis of these issues is crucial for determining the appropriate repair or replacement actions.
