The only thing I haven't done is tested the switch with an ohm meter because I do not know how. Could you please explain exactly what you mean by that i do have a dmm so I can if i know how. And any other suggestions to try are welcome

The washer would not make a difference as long as all of the original wiring was there... Is the switch installed in the dash and the nut tightened up? It has to be to work because that is where the circuit gets it's ground. As far as testing the switch, unplug the connector from the switch and set the meter to the lowest ohm setting, which should be 20k ohm. Turn the wiper switch to the low position and touch one of the leads to the switch body and the other lead to one or the other of the connectors. You should get a reading when you touch the low speed connector (I can't remember which is which). Then turn the switch to the high setting and touch the other connector you should get a reading. In the off position you should not get a reading.
