My apologies, its seems the photos i poached, are not a representation of my vehicle.
This is what it looks like in my vehicle









Just tried using the Stereo System again after having push and pull at the cables that were accessible, the same behaviour occurs
ie: Always the right hand speakers work, the rear left speaker in the door works sometimes, and when it stops, turning the ignition off, locking the car, unlocking it and turning back to postion 1 seems to get it working again for a while.... but eventually (quite shortly) it stops again.
