I've done a search and found nothing that really answers my question.

My passenger heated seat it a bit temperamental - lumbar/back heats up but the base an base-sides don't heat up - .

Is there a guide:
A) for testing the switches, relays and wiring and/or the resistance of the elements?
B) dismantling the seats and replacing the elements in the leather Recaros?

From what i can tell on ETKA there are two replacement elements, (1) back and (2) base that wire straight back to the green plug?

Does the base-element (for the Recaro) also include an new element for the slidey bit on the leading edge of the seat as I can't find any other elements listed?

Thanks in advance - if I've missed a post that answers these questions can you point me in the right direction.

Cheers, Liam
