The Ford Fiesta's windscreen washer pump releases washer fluid to clean the windscreen. The spray increases visibility by clearing away debris. When then windscreen washer pump motor begins to wear out or stops working altogether, it no longer delivers fluid to the windscreen. In that event, replace it. Removing the old pump and replacing it with a new one is a quick job (approximately one to two hours) that requires only a few tools.
Pull the lever underneath the steering panel to release the bonnet. Lift the bonnet up and prop it open with the suspension bar located on the right side of the engine cavity.
Locate the washer pump on the driver's side of the engine cavity. Its a clear plastic bottle slightly in front of the tire.
Access the pump by removing the front, driver-side fender. Unscrew the three screws on top of the front fender in the engine cavity. Use a socket wrench to remove the four bolts on the fender well in front of the driver-side tire. Lift off the fender and peel back the lining by the tire to reveal the whole washer fluid reservoir.
Unhook the power cable by pulling the tabs. Pull out the intake hose. Remove the bolts holding the tank in place with a socket wrench. Pull out the tank.
Grasp the washer pump (small, black device on bottom) and pull it out to remove it from the tank. Use a flathead screwdriver to jimmy the rubber grommet free from the tank. Place the grommet in the same location on the new tank. Place a small amount of lubricant on the inner portion of the grommet. Push the washer pump into place.
Re-attach the power cable and intake hose to the pump. Slide the reservoir into place and replace the bolts. Re-attach the fender and replace all screws and bolts removed in Step 3.
Unscrew the lid to the reservoir and fill it with fluid until it reaches the "Maximum" line.
Hold the bonnet and release the suspension bar. Lower the bonnet slowly and push it down to latch it.
