My tdi defender has front seats from a 2001 merc C32 AMG
All been wired in properly using the merc switches
All was well apart from the heated elements not working so I got some replacement carbon fibre pads and took the seat out to fit them, it's been out a few days and went to refit tonight and non if the functions work
Worst of all I left the seat right forward so I could get the rear bolts out so I now cant drive the car !!
Power is getting to the multiplug under the seat and I can feel the relays on the seat clicking but nothing
Any suggestions ?

Thanks

First thing I would do  is get a spare relay and try that.
Just because the relays clicking doesn't mean the contacts aren't dud.
I would guess there are two fuses, one for the supply to the relay and one for the motor.  Are they both OK?
Often there is a wiring diagram printed on the side of the relay.
If this is the case, pull the relay out then use a length of wire to power up the motor by touching the wire on the socket contact. (Take power direct from the battery).
Still nothing? Then it looks like the earth on the motor is missing.

That will keep you busy.

       Good luck       Pete.

Thanks for the reply
I took the other seat out and I can get the drivers seat to move on all functions when plugged into the passenger side
But neither work when plugged into the drivers side
Strange as I'm still getting powerctobthe plug when I operate the switch

It is strange.
I have seen faulty plugs, when you push them into the socket instead of making contact the pin moves back and stays open cct.
Check all the pins in the plug are solid.
