windsheild wiper switch problems

hate to tell you there's a bad switch here, but we could try to release a 'stuck cam' by if you look where the links for both ww wipers converge, there's a cam and a switch that tells whether or not to continue or to quit. somewhere in that assortment of windshield things there is a pump that pumps the washer...well the switch is stuck, and hate to recommend this but a rap with a screwdriver handle may be just the right thing to put the cam in place...right now can't decide whether its near the bottle or in the steering column...you might just have to trace the washer line -clear plastic to where it gets to the thing what's responsible for getting it to go and do a fonzerelli move rappin it to jockey the cams into the right positions.
