How do you replace washer fluid pump?

To replace a washer fluid pump, first, disconnect the vehicle's battery to ensure safety. Remove the windshield washer fluid reservoir by unscrewing any bolts or clips and disconnecting the hoses. Take out the old pump by twisting or pulling it out of the reservoir, then install the new pump by fitting it into place securely. Reassemble the reservoir, reconnect the hoses, and test the new pump by filling the reservoir and activating the washer system.
