Im trying to remember if there was enough clearance from the front lower bumper area. Its been a while since i took the front end off but Im like 80% sure if you jack up the front and remove the lower plastic splash guards you might be able to access the washer tank, assuming the leak is through there and not the washer motor. Ofcourse the most easiest manner to access it would be to take off the front bumper but its up to you and the outside temps youre willing to work on. I would suspect a loose connection or maybe a split from a poor connection. Thankfully the windshield washer system is more basic than say the coolant system of a car.
My unofficial advice if theres a crack/leak in the reservoir itself would be to jb weld/super glue it but you didnt hear that from me.
