When the multifunction switch is placed in the WASH position, the Steering Column Control Module (SCCM) sends the request to the wiper motor over the Local Interconnect Network (LIN) . The wiper motor then supplies power to the washer pump, which directs washer fluid to the windshield.
You normally need a scan tool to check it.
Yes, if the wipers work and the washer doesn't it's most likely the washer pump. Is there power to it?
The test would have to be done to see what the problem is exactly.
