Whitefish,
I thought Lemoin was in Iowa, and Portland was in Oregon! I was in Portland, Main, this past July.
To add to what Steve provided above, consider the following;
If it is the washer pump motor that is working intermittently, it is most likely a connection problem. It could be a failing pump motor. The pump and motor are at the bottom of the washer fluid tank at the end of the connection (heh heh)described by Steve.
If the pump is "pumping" but the washer fluid is not getting to the windshield, you most likely have blocked spray tips (the plastic tips that the washer fluid sprays through at the end of the fluid hoses). Minerals from "hard" water build up in the spray tips and eventually block the little hole.
The blockage can be remover with air pressure blown in the reverse direction of the fluid flow. Remove the sprayer, carefully as it is plastic and will break easily, and apply compressed air.
Sometimes it takes a piece of fine wire, like a straight pin, to force the deposits loose. The tips can be replaced for about $3 each from Ford.
If the pump has failed, or the pump motor, which also get gunked up with mineral deposits, it will need to be replaced.
I think you will find that an "aftermarket" pump and motor is much less expensive than an OEM (Original Equipment Manufacturer, i.e. Ford Motorcraft) pump and motor. They should be available from NAPA, Auto Zone, etc.
Maybe you will get lucky and it will be just a poor connection. rangerj
