Hi Folks, having a nightmare with rear screen demister, stopped working around 2 weeks ago. Switch on centre dash consul lights and I can hear a click from a relay. Fuse is ok but there is no power to connector under rear spoiler. Cant find the clicking relay to try replacing it. Any idea where the relay might be?
Also Battery is good and still no power when engine running.

What year is your car?

You can’t replace the relay.
Make sure the engine is running when checking for voltage.

I can only suggest you drop the headlining at the back (start at center) and check for voltage before t enters the tail gate

It is a 2007. OK got a few days off work will try to trace if there is a break in cable. thanks
