I just noticed the other day that the front passenger air vent in the middle of the car (right above the radio) is not moving very much air at all. When I have the heat on, the driver side middle vent moves quite a bit of hot air out but the passenger side middle vent isn't moving much hot air out at all. It is still blowing a little, but much less than the driver side. Could this be due to a leak in the system somewhere or a bad fan? I know nothing about the vent system in the car but I do know that it was working fine and then a day ago I turned on the heat and noticed the disparity. Would this be easy to fix?

 

As far as I know (and someone please correct me if I'm wrong) but the two vents in the middle share the same duct but just split to make the two vents. If that's true then both vents should have the same amount of flow unless something has clogged up one vent.

Unless anyone states different, I'd suggest pulling the center console/bezel and checking to see if anything is in the duct.

Just my two cents :shrug:

 

psh mine does it too. I took the console apart for my radio and tried to play with the vent duct while the console was out but it isn't worth it. I couldn't figure it out?
