When the rear windows on my 1993 Discovery 200Tdi refused to operate it turned out the problem was with the relay. It was located at the driver's side panel next to the pedals (remember my car is a LHD) Locating the relay was easy using David's method of hearing which one clicks when using the front windows and then removing the good/operating relay and swapping with the ones on its left and right.
It is more than a year now that this has happened so I do not remember which side it was but it definately was a yellow one (lots of yellow relays). And I was able to find a similar relay from my village's car electrician for the equivalent of 2 UK pounds.
Take care Pantelis
