Can you hear the washer pump running when you operate the washer switch? The washer pump is in the bottom (side) of the washer fluid reservoir. You should hear it running. If not, you can disconnect the wire connector at the pump and use a test light to check to see if there is power and ground at the connector when you operate the switch. If there is power and ground, replace the washer pump motor. If there is no power or ground, you most likely have a bad washer control switch. (You have to replace the entire Multifunction Switch)

If you can hear the pump running, check for washer fluid pouring on the ground. If this is the case, you have a broken hose between the washer pump and the jets that spray on your windshield.

Also note that there is no way possible that your problem could be CAUSED by a fuse!
For more information on this subject, please review this article: Where's The Fuse?
