I'm trying to troubleshoot why my wiper washer will not pump…

Customer Question
I'm trying to troubleshoot...

I'm trying to troubleshoot why my wiper washer will not pump water to the windshield on demand. I've already replaced the pump but no positive results. Next?

Mechanic's Assistant: Have you checked the fuses? Do you know if there is power to the wiper motor?

The wiper motor works fine; would there be a different fuse for the pump?

Mechanic's Assistant: What is the make/model/year of your car?

1990 Chevrolet C1500 Silverado truck

Mechanic's Assistant: Are you fixing your Silverado yourself? What have you tried so far?

Yes working on it myself and so far just replaced the pump/motor in the reservoir.

You refused to analysis this via chat, I'm no longer interested and have requested a refund.
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 2 months ago

TO be honest sir, that is not true. I would rather do this via chat.

The web site sends "automatic" phone call offers. That is not me. I do hope you understand.

Okay fine. Let's continue if you have something else to offer.
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 2 months ago

Most certainly. Have you checked for power and ground going to the washer pump? If so, do you know what is missing preventing the pump from running? If not, this would be your first step.

Also, have you checked the fuses?

Ask Your Own Chevy Question
Customer reply replied 2 months ago
Would there be a different fuse from the wiper motor fuse?
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 2 months ago

No, it is the same fuse

Ask Your Own Chevy Question
Customer reply replied 2 months ago
if the wipers are working then the pump fuse is fine. What's next?
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 2 months ago

Checking for power and ground to the washer pump when depressing the washer switch.
