Hi ive recently brought a 6th Gen Celica in the summer, and ive got a problem thats just started happening, The windscreen washer will turn on by itself and empty all the water on my windscreen!! the pump stays on until i turn off the engine and restart it and the pump is off. So i know its not the pump anyone know where the relay is or is it a wiring problem elsewhere along the circitry or in the
dashboard console/steering wheel i need a new stick??

Tried a google search couldnt see anything in proper realtion to my car

Thanks in advance!

if I could guess I'd guess that it's in the switch, the rest of the system is pretty reliable stuff unless someone has hacked up the wiring along the way.

all the circuitry is either in the switch or the pump itself, i dont see a relay on the EWD
