I have just bought a 53 plate Cayenne S, I cannot get the heated seat to work. I have checked the various fuses it could be. The switches light up with the lights on but no heat is coming out. Any ideas on what this could be?

What is a "53 plate Cayenne S"?

The seats take a little while to warm up, how long are you waiting? Also - I'm not sure they work if the outside temperature is not cold. Is it cold where you are now, or are you just testing them out in a warm area? I may be wrong on this issue... I know my old Saab was like this, but I'm not sure about the Cayenne.

It is about 5 below at worst, I can feel the steering wheel heating up but not he seats?

Are the seat heater switches on a Cayenne like the switches on a Boxster? That is, are they "3 position" switches where you press on the front of the switch for "Off", press once on the rear and a red light goes on for "High" and press again on the rear and a yellow light goes on for "Low"?

If so, could you please describe the exact symptoms, as your problem may be related to a faulty relay under the seat.

Regards, Maurice.

No, it's a wheel with 5 positions, 5 being the hottest.

It might still be a relay. If only one of your seat heaters is malfunctioning, it might be worth swapping left and right switches and left and right relays for each other to narrow down the source of the problem.

It is a UK car, and the registration plates are date-related. 53 is late 2003/early 2004.
