    Where does the power come from for the powr windows; can't find a fuse, can't find a circuit breaker. sometimes they work, sometimes not. got new switch too.

    On mine there are two relays to the right of the columb,way up there near the left of the radio' one is a big silver one which i think is for the rear defogger, and the other is the power window one; this one has three wires going into it, to find out if the problem is a bad ground, turn the ignition on and wiggle the relay around abit and if it starts 'clicking', sure-as-poo thats what it is.

    I have a big silver relay mounted on the left of the radio like you said, it has two big fat wires running to it, one orange with a white stripe and a purple with white strip, then a small.. i think green wire, and two small black wires running to the same plug.
    if you take the relay off it has 3 plug ends on one side and one on the other, sound right? or is that the rear defogger?
    i dont see any other ones under there.

    Thanks, hopefully soon i can find the problem.

    Got it, it was the power accessories relay in the fuse box, i had a 30 amp fuse in there but they still didnt work, snapped in a 30 amp breaker and presto, windows!
