Mazda6 rear vents airflow weak
« on: March 01, 2021, 08:33:13 am »
Hi
I bough a used 2017 Mazda6 Tourer SE-L NAV D 2.2litre diesel couple of weeks ago (never owned a Mazda before). I noticed that the rear air vents (for the passengers in the back seats) blow the air with much less power than the front air vents. I'd say the air blowing in the back is about 10-20% when on lower air flow settings and maybe 20-30% on the higher air flow settings, comparing to the front air vents. I would expect the air flow to be a bit weaker in the back than in the front but I have no idea how much weaker it should really be.
I would really appreciate if someone can advise on the below questions:

1. How much weaker airflow should be from the rear air vents comparing to the front vents?
2. Is there any additional fan/motor in the back to propel the air flow to the rear air vents?
2a. If so where is it located and how to access it?

Thank you

Do you have warranty for your new to you car?

Is your cabin filter in good condition and fitted properly?

Are the rear vents for the air conditioning only?

I do not think there is more than one motor doing all the air circulation. So logically speaking, the rear vents could be less effective.

By having a cabin filter, you do not really need to clean up the fan motor.
