how could i get a shortage fixed in my ipod
Am I correct in understanding that the audio ONLY plays in the left side?
The first thing to try is to make sure your data is backed up and restore the iPod.
If that doesn't help, it sounds like the headphone jack is bad, which is soldered onto the logic board. You'd need to replace the logic board to fix the problem (it may be possible to fix the problem with solder, but the components are so small and fragile that this is VERY difficult).
