I was successful in inserting a wire in both ends. It seems that the wires made it to the 90 degree bend. I then squeezed in BD Blaster thru the plastic straw. I had flow of the fluid, dripping out the other end.

So, what now do I do to increase the opening in the tube such that there will sufficient open size to allow the vacuum to operate the wiper?

Thank you for the help thus far.
