Rear washer not 'squirting'

[85 DSEL]

NOW is the time this feature is needed here in Ohio! This car is new to me in August so not sure of the history on this feature - all I know is there's no fluid hittin' the window when I push the little button!

Where should I start? The car is a "well cared for" and it really is evident. There is fluid in the rear reservoir (gotta love the spell-checker !)

Thanks for your comments...
