Help please.....is this an ECU problem?

Hi all,
I've listed this on the Range Rover forum (no joy yet) but its really a general question for anyone practising the black art of electrickery....I have a 1993 TDi Range Rover whose front windows have just packed up within a couple of days of each other......which is ideal in this hot weather!
The rear windows still work without a problem so I've tried changing over the switches and the relays but its not these.

So, could the window lift ECU partially fail, or would it pack up completely so that I'd lose both front and rear windows?
If it isnt the ECU then the only other thing I can think of is that both front window motors have failed within 48hrs of each other.....what are the odds!?
Cheers

Have you checked fuses?

Doh! :doh:
Was convinced that the two front windows had failed on different days and was therefore distracted from the bleedin' obvious.......a fuse!
Thanks! Thats saved me £20 on ebay.
Cheers
