Hello,i Need Some Help Regarding The Rear Air Outlet,when The Heater Is Working The Warm Air Is Coming Out Only From The Front Vent`s And Not From Thr Rear,wich Blows Cold Air Only.

Thanks

Marino

I believe that is correct that way. Shut that vent tightly. There should be two flat ducts under the front seats for heating the feet of the folks sitting in the back.
If I remember right, the center vent is either just a vent, or with the a/c on, a a/c duct.
