Electric Seat Relays; How many are there?

I'm still trying to find a fault with my electric seat and thought I would investigate the relay side of things.

How many relays are there for a driver's electric memory seat? I assumed there my be two, but went to MB Chesterfield and they can only find this one;

Seat Adjustment Relay: Part No - 0015422219 (£17.80 + VAT)

If there is only one relay, then I presume my problem does not lie there, as other seat functions work, or (excuse my ignorance) can a relay fail in part and some functions will still work?

I've checked the following so far;

Switch - The back of the switch looked o.k to me!?

Relay Box - Replaced the two 25 amp fuses shown, just in case!!

Any ideas?

I'm not being funny but you did check the right relay, that is the black one in your picture.

And those two fuses are for I think 'Left' seat Heating and right for the heater blower.

That's right I think the 'Control Unit 'is in the door, not sure though.

Thanks for the responses - it's like magic this problem, as it's hard to get the old head around !!

balamb37 - The relays you can see are how and where they were when I bought it - I only took them out one by one and re-inserted them to see if that, as suggested, might work!

Papa - Thanks for the expanded parts' pictures. Control unit, Ive no idea where it is located - the only unit in the door is the picture showing the back of the seat switches, or perhaps it's the actually the control unit!

ChrysAk - There must be more than one relay, as you say, as the one in the diagram is for the Headrest, whereas the one I referred to is the Seat Adjustment Relay. The headrest does work though, as does the for and aft seat base movement, and all the tilt movements. Just the backrest and memory functions on the blink!

Any more thoughts?!!
