SLK320 Sulky Seats

[PHUNN]

The s..seats s..till s..top and s..tart when it s..uits them.
Can anyone please tell me where in the car the relay (and /or the 'sender') for the seats is located, and where I might buy a new one?

Came across this plea from my past and thought, for any future sufferers, I would update the history.
After various tests/checks/head-scratchings by a multitude of mechanics, some of whom were of the very expensive Merc variety who wielded their electronic gadgetry to no avail (except their bank balances) I INSTRUCTED a change of relay (and not by the local Merc. dealer).
Guess what: all, immediately, became right.
Cost; it was a long time ago but maybe £25?
Never did find out where the relay was located tho'.
