2013 Escape SEL with about 57K miles. Both the front and the rear washers don't squirt. Not sure when this happened, whether both went out at the same time or not. For both the front and rear, when I activate the washers I can hear the pump working, but no fluid comes out. Looking in the engine compartment and on the garage floor, I see no evidence of fluid leaking out anywhere. I guess I haven't checked the rear headliner for leaks up there. It's so damned hard to get to the bottom of the washer fluid tank--I don't want to do exploratory surgery unless/until I know that I'll be able to fix it properly. Any ideas?
