Well, changed the tailgate latch and................Nothing!

No difference

Messed about with this & that, but nada.

Then I decided to look at the LED's I had installed instead of the single lamp on the top tailgate.

Touched the wiring and lights went out (they had been timed out, but were staying on...). So I wiggled and it flickered.

I can only imagine the green on the pins were sending spurious signals to the BECM as it seems to have stopped with a good spraying from the switch cleaner

We'll see

FLASH INSPIRATION FLASH

I know what the cause is!

The day this all started, I'd had my car washed at a different place!! I usually get it done professionally, but a mate owed me a favour so I let him wash it...

I am certain the problem was caused by a leaking wiper motor rubber. When the car gets washed, water seeps in and runs down the rear interior glass. It obviously makes it's way to the wiring and the connector for the interior light. What a pig to find, but now I know the cause, I am planning to cut the connectors out altogether, then solder & heat-shrink the wires. Hopefully that will end it all for good.
