I have a 63 plate Volvo. When I set the night heater timer on the dash to come on in the mornings it just doesn’t. I make sure its got the right time even set it to go off daily but it makes no difference it still never works. I’ve tried setting it at night when im sitting and some times it works some times it doesn’t. I’ve tried setting the temp from 20 def to 25 and still makes no difference. Can’t understand if its something im doing wrong or it’s a fault. The small symbol shows up to let me know that it’s set as well. Any help would be appreciated.
My 64 plate Volvo is the exact same, timer says it’s on but it never kicks in! And the heater is over on the passenger side aswell just to really get on yer ■■■■ 
My 16 plt MAN works a treat [emoji16]
