B12E8-23 (2F) Liftgate/tailgate control release switch - General signal failure - signal stays low.

I assume this is more likely to be a broken wire somewhere rather than a problem with the button.

Any suggestions on where to start looking? Or information on the wire colours, etc. to look for?

Thanks.

Any thoughts?

Does the tailgate not release then? I assume you mean the upper? Does the key release it?

The button on the top of the lower tailgate has suddenly started to misbehave. It does open sometimes, usually after a bit of jiggling around.
