    My drivers side heated seat doesn't appear to work even though the buttons on the door function correctly. I am guessing therefore that its probably the element although it seems odd that both the back and bottom bits have packed up simultaneously. According to the previous owner this happened before and it was replaced by a main dealer (Greenoaks in Slough) at a cost of around 400 quid around 4 years ago.

    I just wanted to ask if there are any pointers to help me diagnose the problem without having to remove the seat (which seems too complicated). Can access be gained without a full removal of the seat?

    if both back and base are not working then double check fuses and the connections under the seat where the wires plug into the loom on the foor.

    I agree about the fuses, I have checked the one under the bonnet and its ok. I think there is another in the box under the rear although I cant work out why there would be two fuses!

    Quite hard to get to the control box under the seat but I'll see if I can remove the connectors and reseat them

    This is fairly common on SLK R170 and C W203 models with AMG seats due to the element being integrated with the seat cover.

    Find out if the element is integrated into the seat cover, or separate. If separate, slip another in. If integrated, either replace the seat cover, or slip in a separate element.

    Hi mate, thanks for the response but a couple of questions...

    Short of stripping the seat down is there any way I can find out if the element is integrated or separate? Impractical for me to strip down the seat as the car is my daily driver to work.

    You mention slipping another element in, which sounds interesting have you done this? I like this approach, it could mean I could purchase aftermarket one like those of Fleabay and splice it into the existing wiring. Just wondering how I could do the slipping-in part you mention!

    Cheers
