Ahh ok sea what you ment by a pad now, i presume its like the heating elements under the floors, i also thought it was just the bum that was heated!
So the back is heated too, need to check the HGT to see, and the volvo, as havent noticed the back getting warm!
well you know what they say, just be thankfull that most of the stuff works!
Also how easy is it to take the seat covers completely off an then get them back on? As mine could do with a dry clean! due to the last owner!
