The seal in question. I don't know what you call it but there's this "strip" of trim above the licence plate area, attached to the very bottom of the tailgate. For example if you were opening the tailgate using the release button your thumb would be on this piece of trim. That can be removed by undoing three or four torx screws on the bottom of it and then the seal in question is visible between the strip and the bodywork.
Mine had almost turned to dust it was that perished !

Hi there,
The moisture gets inside and shortens the circuit.
What I've done with mine was removing it for examination,finding that if the right light(license plate) bulb was installed it would get a short circuit and the button wouldn't work at all..it worked fine once the bulb was removed,so I bought it inside and dried inside with the hair dryer.
Also the connector inside of the housing was loose and I suspect it was where water accessed through into the otherwise sealed plastic capsule.
So I used the glue gun and sealed the connector hole as well gluing it,so there's no play at all.
It's been two or three months and never had the problem,and we've been through the worst winter I've ever seen.
Before I fixed it I would turn off the engine and would get the hatch unlocked or turn on/off the lights and get the same result.
Good luck
