fixing air flow problem
i had the same problem in my car and found out it was as simple as connecting the dail back up. If you lay on your back on the floor of the driver side of your vehicle looking up, you should be able to see the steering column. if you look more to the left you will see what looks like a round silver piece with a black stick coming out of the center, which connects to a flat triangle piece. Both pieces have should be unconnected. if this all confuses you, have some one else turn the dail on panel while you look up under the dash. you will see the black stick moving up and down. this operates the flow of air to floor, panel, or defrost. hope this works for you did for me.
