Hi guys just a quickie I've noticed my rear heated screen on my 2006 2.7 rrs is not demisting
I've checked the fuse an that's ok and there is no breaks in the lines on window or small side windows either
Any ideas ??
Cheers

Good chance it is a corroded connector under the roof spoiler:

Note: The replacement connector pictured in the 2nd page of the thread doesn't look man enough for the job: I bought one but didn't fit it because the terminals look too weedy for the current passing through that circuit. 2008 MY Java Black TDV8 HSE

Yeah I have read it could be that just wanted to check before I remove the spoiler
Is there a relay for the back window heater has I've looked in manual and carnt find one
When I press the button on dash it Dosent click but still lights up

There is a relay. You can hear a very faint click from the passenger footwell area when switching on the screen heater. The lines in the side windows are aerials BTW not heating elements. 2008 MY Java Black TDV8 HSE

Oh right thanks.good info! Which relay is it ? And where passenger fuse box or engine?
Cheers

Without searching through the workshop manual - can't be sure but certainly sounds like it is on the passenger compartment board. Never had to do it myself but others have reported getting to the relays in that area is a right PIA.

EDIT: The relay is no. 138 on the Central Junction Box (CJB) - which is in the passenger footwell.

Removing the roof spoiler is a 5 minute job so why not inspect the connector under there first? Relays that are rarely used don't usually fail so I doubt that the relay is your problem. 2008 MY Java Black TDV8 HSE
