When you press the lever to engage the windshied washer in the '72 I get nothing. The hoses are all dry, and the main tank has washer fluid. Can the white pump, at the motor, be replaced, or the whole motor?

check a good auto store, or internet.....there are just the pump seal rebuild kits, & also the whole pump motor too.....you may take it apart & tinker with it, i was able to figure mine out & made it work again with a seal kit....g.
