How to Install a Wiper Fluid Motor
The wiper fluid motor in your vehicle acts as a pump to distribute windshield wiper fluid through the wiper system and onto the windshield. When this pump fails, you won't be able to spray your windshield with washer fluid. If the washer pump motor sounds strained or it is not spraying properly, this is a clear indication that the motor needs to be replaced. Replacement motors can be purchased from most auto parts stores. This job should take 10 to 15 minutes.

If so, you will need to remove these bolts with a socket wrench and pull up on the reservoir tank to remove it.
