I am trying to get the windshield washer operable on my 57 Olds. Unfortunately, there is no diagram in the shop manual that I could find that shows the lay out. Does anyone know how many vacuum lines go to the washer controller behind the dash of a 57 Olds (no AC) and how it's laid out? Any help would be greatly appreciated.

 

'55- from water jug to squirters(supply); from jug(vac.)to front of switch in car; from switch in car to vacuum source.
Hope they are the same. Gool luck!

 

for my '55...yours should be pretty close

 

Thanks to you both for the information - sorry it took so long for me to get back, been away awhile.
