Air sometimes comes in through passenger side vent

[CDP110]

Hello. So I drive 90 miles each way to work and it has been nice outside so no heat or ax needed. Someti
Es when I’m driving u hear a sudden air noise coming through the passenger side vent do a bout 5 to 10 seconds then it stops. Very weird. With all the new technology I didn’t know if it does that to equalize the cab

Happens to me too. I don't think the cabin equalizes like an airplane or else the doors wouldn't close. I believe there are flaps in most cars for this purpose.

My truck does the exact same thing when I have my ac on. I haven’t noticed it when the ac is off.
