A couple of issues....windscreen washer and power steering

[MasterOfReality]

First problem:

My windscreen washer does not work anymore. When I press the button, nothing happens. I think the button is stuffed because the windscreen wipers would still work when I press the button.

How do I remove the button without busting the switchbank???? Can I buy a new button from Holden or am I forced to buy the complete unit?

Second problem:

I have posted about this before, so sorry about the repost. My power steering doesn't seem to work anymore, but the pump is fine. I heard something about a valve in the rack??? Its got the variable power steering. Anybody else had problems with this?? How much did it cost to fix???

Thanks all

could be the motor on the window washer bottle, check it by puttig power and earth direct to it. Also if you get a test light and check for power and earth on the wires on the washer motor that will tell you if the switch is workin.
Dont know about the steerin
