2003 Mini Cooper S Windshield washer

There is only one washer pump that supplies the wash to the windshield and the rear window. When I PULL the wiper/washer wand down it is suppose to spray the windshield. That doesn't activate the pump. When I TURN the wand knob down it DOES activate the pump and sprays the read window. At the pump there is only two wires on the connection. There is 2 tubes, one going to the windshield and one going to the rear window. I switched the tubes and when I PULLED the washer wand(to activate the windshield spray) nothing came out, front or rear But when I TURNED the wand knob(to acti vate the rear window spray) it sprayed the windshield. So, I think we are looking for a switch, or connectiion, or inline fuse that is not allowing the electrical continuity when PULLING the washer wand(for the windshield) to activate the pump. Where it is allowing the current to flow to the washer pump when I turn the knob for the rear window spray.
How and where do I check connectons and current flow or what do I replace?
Thank you

In the fuse box that is located on the driver's side footwell there is 3 relays, RL1 for the Gas, RL2 for the Air Conditioning, and RL3 for the Headlight washers. I did switch them around and found that nothing work differently.
I also checked the regular fuses F25(30a) Headlight washer, F23(20a) Windshield washer, and F17(15a) rear window wiper, they were all good, but I replaced them anyway.
In the Engine Compartment fuse box, I checked the Relays R5 Front windshield, and R7 Rear window, and fuse F9(20a) windshield wiper. All good.
The wiring diagram I have shows 2 other relays between the washer pump and the steering column wand(switch): A 'Front Washer Pump Relay' and a 'Rear Washer Pump Relay'. If you could tell me where those 2 relays are located, I could check those, and I think we will have checked the entire circuit.
