There's a relay under the carpet by the left hand runner of the passenger seat.

that gives problems and causes failures.

 

These seats are know for the heaters not working properly unfortunately, mine have never done

both mine dont work either but switches light up..did buy a heated seat module/relay months ago but not fitted..think the passenger seat needs lifting up as its situated under this

Should try mine I guess. Only had it 5 days and it’s summer so I never thought to try them lol

The relay is not too expensive, loads of them on eBay, and it's not too tricky to replace so it's worth trying that first. 

Does anyone have a video of where to find the wiring connectors?  I've been told it's under the carpet?  Someone said the connectors may have come apart.

The plugs are under the seat beneath a flap of carpet - they are very secure it would be hard to imagine them coming loose on their own however they could have been unplugged. The absolute easiest way to see it is to remove the 4 fixing bolts for the seat rails and tilt the seat back so it's laying on the rear seat then access to the plugs and the relay is super easy, you do need the spline tool to be able to do this however - they are not too expensive on eBay.  Otherwise it's tricky for access with the seat still in place but not impossible.

Any idea what colours are the heating pads? I don’t appear to have any heating on mine (based on a cursory 5 min button press in summer 🤣)
