Start by verifying the pump will run. Remove the windshield washer relay. With the key on and your voltmeter set to read voltage, check for 12v at terminal 5. If power is present, momentarily connect a jumper wire between terminals 5 and 3. The washer pump should run. If not, look for an open circuit between the relay socket and the washer pump.
If the above test worked and with the relay still removed and key on, switch your meter to Ohms and connect one probe to terminal 1 and the other to chassis ground. Push the washer switch, you should see 1 ohm or less.
If not, plug the relay back in and go to the multifunction switch connector C212 at the bottom of the column (leaving it connected). With the key on, momentarily insert a jumper wire between Pin 14 (Light Blue with Orange stripe wire) and Pin 13 (Gray with Red Stripe wire). The washer pump and wipers should run. If not, the problem is more than likely with the GEM or its associated wiring.
