Hello my name is XXXXX XXXXX I will be more than happy to assist you.
The Windshield Washer Pump gets its power from the WIPER 25 Amp fuse.
If the wipers are working then the fuse is good.
If the pump has stopped working then the problem is either the Pump, the Wiper/Washer Switch, or wiring from the switch to the pump.
If you need help finding the cause please let me know.
