My Hicas light came on, and climate control stopped working.. checked all fuses and they're ok. Buttons on climate control does light up, but if I press them .. it doesn't do anything, screen is always off, not woriking.. any ideas ? Looks like power steering & climate control are kind of reliated .. they stopped working both at the same time.
I can't get into hicas diagnostic.. and I didn't change anything to the car.
