If a customer comments that there is windshield washer solvent leaking from the front driver's side of the vehicle, this condition may be caused by a cut or not properly seated washer pump grommet.
Before replacing the washer pump, inspect the condition of the grommet around the inlet of the washer pump. First make certain that the pump/grommet is fully seated in the washer solvent container. If a leak still exists, then remove the pump from the
container using care not to tear or cut the grommet during removal and inspect the grommet to make sure it's free of cuts or tears. Install the pump and grommet back into the container making sure to use washer solvent to lubricate the grommet. Inspect for
leaks again. If the washer solvent still leaks, be sure to inspect the outlet hose for a proper connection. Make every effort to inspect all components before ordering a new part.
DO NOT
replace the washer pump unless you see that the pump is cracked or broken externally. If the grommet is torn or cut, replace only the grommet.
