Electrical short - smoke from left rear - 2002 Liberty
 

Hi all,
On my way into work today I smelled a burning plastic smell, looked in the mirror and was delighted to see white smoke coming from area behind left rear wheel (below tail light assembly). Emergency flashers and turn signals don't work, so assuming it is likely a short near the tail lights themselves.

So I got it towed home, and am looking for suggestions for investigating. Is there an easy way to access the wires in that area? I'd like to avoid taking the whole arse end apart if at all possible. :)

Thanks,
Kris
