I suddenly lost my power lock, mirror retract, power window, parklight, taillight and aircon blower all at the same time, the rest are fine.

The bus is a Lucida Estima G 1992.

I have checked all the fuses and they are all good.

Could it be a relay problem?

I hope you could post some tips as i could not find a good electrician, they always complain that they don't understand japanese.

you may also post shops you know.
