A friends Toyota Vitz model 2009, 2012 import is having power steering issue. The power steering turns off(steering becomes hard) sometimes when he comes to a stop at a traffic signal, then when he gives the engine some revs it again starts working.
His car got washed first time from inside the bonet(without his knowledge maybe by brother) from a service station. There is also some water in the left side front light.
What could be the issue and possible fix for this issue

Just noticed something , the problem only occurs when the steering is put into full lock on either side.
locked it 5-6 times to check and the same thing happened again and again.
