This morning while drving to uni decided to turn the seat heating on, when i pressed the button the lights came on for about an second and then just turned itself off, a bit later it seemed to work, my butt was warm for about 2min  and then it turned itself off, now when i press the seat heating button, it comes on and then shut itself off. Checked fuses, they seem to be ok. Thanks in advance

As i don't have this on my car is the time it is on dependant on the heat already in the seat so if at temp it will not activate?

Or is switch knackered!

Welcome MarKo,

Sounds like a warranty claim, assuming it is a more recent model?

Being an intermittent fault I'm guessing the earth or power wire to the seat is damaged and thus shorting out.. Try moving the seat one notch forward or back. If it starts working or is completely dead then that would confirm, to a certain extent, that the connections are dodgy.
