I have a November '94 Saab 900 S with the following problem:
When I press the button on the end of the stalk, the rear screen is wiped but the screen wash is sprayed on the front screen.
Unfortunately the Haynes manual and the owners manual don't tie up so I am trying to find out how the pump works before I take the bumper, and the inner wing, off.
I am guessing there is a single pump with relay actuated valves in it for the front an rear screens.
Any help would be greatly appreciated.
Cheers
Alec
