If you swap the left and right speakers, and the left one still
does not work, then it isn't a speaker problem. It could be wiring.
Try swapping the right and left speaker wire at the amp end. If
the problem swaps sides. But more than likely, you are losing one
of the amplifier channels. With a 10 year old amp, and moving the
volume control fixes it, I suspect that you have dirty controls.
Try cleaning the controls with a good spray control cleaner.

This sounds like dirty or oxided switches in the receiver, for
instance the input selector. Try flicking the switches back and forth
10-20 times and see if that clears it. If it does, you can fix it by
opening the box and cleaning the switches. The same is true for the
safety relay as another poster reported.
