Rear screen heater

[markd]

Hi there
My Brava rear screen has stopped working.Fuses are all intact and the dash light comes on, but no heat.
Could anyone point me in the right direction?
I know summers on the way and it's not so important but I'd still like to get it fixed.Can I meter power to it from the tailgate contacts and if so which one is it? I'd really appreciate some help.Thanks.

Is power getting to the heater elements, can you rig up a test lamp to confirm? The lamp on the dash may well come on but it doesn't mean power is reaching the back end.
