Ok...There are 3 pumps on the Reservior. One for the Headlight System, and one for the Front and Rear Systems ash shown in this removal diagram.
It is starting to sound like the Pump Motor for the Front and Rear systems...Or the Switch. As complex as they are making vehicles these days, the Washer System is still really basic. There is a Relay for the Wiper System located in the Under Hood Relay Box. It is possible this Relay is not triggering off the system.
We need to make sure you are getting Voltage to this Relay when you turn on the Switch. If you do have Voltage here, and the relay tests out, then need to make sure you are getting Voltage to the Pump Motor. If you are getting power to the Pump Motor, then check for Resistance at the Pump Motor. More than likely you will not have any, thus resulting in the Pump Motor replacement. If you would like to continue to test the Relays and Pump Motor, let me know. A Voltage Meter will be required for these tests.
I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JHoop
