Hi
 
	 
 
	Ever i since bought my 2011 XJ the rear window element does no appear work 
 
	The switch light is on 
 
	The rear screen was re tinted when I bought it. is there any way to check the element
 
	The screen seems to clear slowly, does it have heater vents that blow on it?
 
	Any suggestions would be appreciated
