Aux jack on Touring w/o Nav-Audio Problem

Cmike2780

So I usually hook up my iPod to the Aux jack and works fine. Today however, I notice that sound is only coming from one side of the car. I've already checked the following and it still happens:

Balance control: at equal. no sound when you turn it towards the side with no sound.

Other inputs (FM/SAT/CD/BT): working normally (sound from both sides)

Aux. Wire: Tried several others, same thing

Device: Tried the iPod, iPad & Phone (all devices are working normally)

Sometimes it works fine for a few minutes, then cuts out. I'm hoping its not the stereo, but it seems the only thing left. Has this happened to anyone else? Would the dealer install a new stereo or is the Aux port separate?

Note: Stock Touring radio w/o Nav.

Thanks in advance.
