'97 wagon T5 turbo: front window washer won't work

[chasen]

Pump is working.
Rear window washer works, but found a leak to headlights. Can't reach it.
To test the windshield, I disconnected working hose from headlights, then attach windshield hose to working pump,and nothing happens to windshield sprayers. Without hoses attached, the pump really sprays out the fluid.
I cannot see how to check hose to windshield,as goes in space above the tire well. Then checked up by hood hinge and up into engine hood. Checked hose over to sprayers, nothing looked wrong.

Dealer mentioned check valves, where are those and how to know if not working?

The check valves are under the insulation on the bottom side of the hood and they fall into the "usual suspect" category.

Follow Lee's instructions and look at the T joint under the insulation in the hood. A lot of times those fail. It's failed on both my S70s and my 850.
