2004 (54) Corolla Verso Front Camera

[Lamp16]

On my Corolla Verso T-Spirit it has the front dual camera's for pulling away at junctions. I think that there is maybe a loose wire, as most of the time they do not work, but occasionally when I switch them on both have a picture but only for a couple of seconds before scrambling up again.

I have had a quick look and cannot work out the easiest way to access the back of the cameras to have a look. Has anyone else had a similar problem with theirs and could they offer any advice on what to look at?

Thanks
