Then your Radio is the problem. The radio actually powers the front panel known as the printed circuit board. Once that is powered by the radio, it powers up the Air controller.
What I normally like to recommend to customers when this type of thing happens is to remove the radio and get a radio install kit and install a after market radio. This way the cost is cheaper than replacing the radio and you will avoid any future issues with the printed circuit board. When you get this after market radio install kit. It eliminates the printed circuit board and then you can select any type of radio you like. One that has more up to date features, such as Bluetooth, USB or IPod. To repair the radio you would be looking at a cost of around 499 or more to repair. That doesn't include labor. The radio install kit and depending on the radio you pick could be cheaper. That is why I recommend it.
Here is a few links showing the radio install kit, and what a after market radio's look like in your car.
