What is the reason for the lack of airflow from the rear vents in the new RAV4?
2 Answers
New RAV4 rear vents not blowing air may be caused by air leaks or issues with the cabin air filter. Presence of air leaks: There may be air leaks at the connection between the evaporator case and the air ducts. If there are air leaks at the connection between the evaporator case and the air ducts, the cold air that should be released from the rear air vents continuously escapes from the leak points, resulting in no airflow from the rear vents. Issues with the cabin air filter: The cabin air filter is located at the intake of the blower motor. All cold or hot air blown out by the car's air conditioning system must pass through the cabin air filter. However, the cabin air filter is prone to accumulating dirt. If the owner does not replace the cabin air filter in time, a large amount of debris can easily accumulate on the filter. This debris naturally reduces the airflow passing through the cabin air filter, leading to no airflow from the rear vents.
As a veteran driver with over 20 years of experience, I have considerable expertise regarding the issue of rear air vents not blowing air in the new RAV4. The most common cause is incorrect AC settings - perhaps the rear air switch was accidentally turned off, or the mode was set to front/feet-only airflow. Another likely culprit is dust or debris clogging the ducts, especially in vehicles that have been used for several years where dust accumulation can block airflow. If the blower fan or motor malfunctions, the rear vents won't receive air either, requiring professional inspection. Last time I encountered this issue, cleaning the ducts solved it. My advice is to first check your settings, then inspect the vents for obstructions. If these steps don't resolve it, consult a professional to prevent potential damage to the entire AC system and ensure driving comfort and safety. Remember, a dirty cabin air filter can also indirectly reduce airflow volume - regular maintenance is crucial.
