Does anyone have a fuse box diagram for a 1990 Lexus LS400?
Did you maybe hit the window lockout switch on the driver's door? Which fuse panel were you looking for- under the hood or driver's footwell? I have a '92 and just checked and both of the covers list what the fuse goes to. They should be the same- Gen1 M1, so if yours is missing, I can pull mine off and try to help. And congrats on the purchase!
