Thanks to all who passed on info regarding why my rear window heater does not work...but...I've checked the relay (which is o:k) / soldered a 'by-pass' wire @ the rear connector (on the passenger side rear).... still not working ...Any further suggestions? Also the interior heaters not working...renewed thermostat / checked pipes ..all getting hot o:k / on accelerating a 'gurgling' noise can be heard fron under the dash & the heaters start to * hot air. I know there's a lot to digest but I'm totally stumped..

Thanks,

Ricky

Sounds like you need a new heater matrix mate or you need your colling system being bled through!!
