On mine ('88 Valver) you look at the fuses, and the the relays above them, and above them there is a small silver circuit breaker and to the right of that is the Window relay.
I had to remove the terminals from the connecter block and nip them then refit aswell cos they were hardly holding the relay in (did this b4 getting a new relay)
If you still can't locate it let me know i'll take a pic and circle it.
