Help: Prado Electric Window Switch

[radioman]

Hi All

the other day all my windows stoped working, fuses all ok, so

i thought that i will look at the master switch, well it all looks ok to me

so i used some switch cleaner to clean it, and refitted it.

I could not get the drivers window to work, but the passanger and rear

windows worked if you used the switches in the doors, but would not work

if use the master switch!

But today none of the windows work

also when i went out in the car, i could hear what sounded like the doors trying

to lock\unlock, maybe this has something to do with the master switch (door lock

button).

Is there anyway to test the operation of this unit ??

Thanks for any help given
