I've been noticing a problem thru my ac vents lately.
I was doing about 40. My windows were all closed and i had the ac off.
Suddenly, my vents start pouring out a little bit of hot air . the switch is on the red side.
when i switch it to the blue side, it pours out cooler air .again, the ac is off.
did anyone have this problem before and how did u fix it?

 

if you want the air to stop coming in the vents, switch the airflow to recirculate.

 

tried it, still the same thing happening...is there a possibility that something might be loose or need replacement?

 

the motor that moves the vents could be messed up...
