Water pump and windshield fluid - 1988 Mercury Grand Marquis

Get someone to use the washer jet while you listen by the washer bottle. If you can't hear the noise of the pump working, it has more than likely failed. There is a possibility the washer switch has failed. A test light on the washer pump plug will tell if the washer pump circuit is working. Hook up the light and press the washer pump switch and it should light up. If both the washer pump and switch appear to be working, the jets are clogged and/or you have a split line (obvious due to water leaking from somewhere) A tip - don't use additives and use rain or distilled water. Detergents can attack rubber seals and tap water can cause scale to build up (plus it will leave water spots)

no same tank but two pumps possible clog of line and or nozzle pull hose off nozzle and try to see if fluid squirts if yes use a pin or air or clear nozzle if no fluid possible pump in washer fluid tank shot

A washer pump in a car's windshield wiping system moves washer fluid from a reservoir through hoses. The motorized pump pressurizes the fluid to allow it to be squirted from the hoses through nozzles onto the front and/or rear windshield of a car. The washer fluid helps windshield wipers get rid of rain, dirt, or other objects that can interfere with a driver's visibility. If your washer fluid is not being sent out when activated, the solution could simply be filling the washer system's reservoir with more fluid or cleaning the nozzles and hoses. In more severe cases, the washer pump may need to be replaced. Here are steps to troubleshoot a windshield-washer pump.

Windshield Washer Pump and System Diagnosis

it locate in tthe bottom of windshield water reservoir(tank)

check the water pump placed under the water bottle or switch the car on dont start it run the water if you dont hear the sound of water pump running its either the pump damaged or something to do with the fuse or wiring

The most common problem I find in this season, is having summer 32 deg. F freezing windshield wiper fluid in the tank rather than -20 deg. F freezing windshield wiper fluid.

Try to warm up the car by parking it in a heated garage until the windshield wiper fluid thaws. Then, try to use it all up, and add the 'winter' vs. the 'summer' formula of windshield wiper fluid.

If this does not solve the problem, the pump might be burnt out, in my experience.

You should hear a humming sound as you depress the button for windshield wiper fluid inside of the car.

Good luck on this repair.

First of all, try to warm up the car to above 32 deg. F so that any ice may melt in the pump. Check that you have -20 deg. F windshield wiper fluid vs. the 32 deg. F fluid for the summer. Flush out any summer windshield wiper fluid. This will help to get it ready for winter which is already in full force.

If you still can't hear the pump humming or spinning, then try to replace the pump which is located in the plastic tank in most cases.

The fuse usually will not blow on the windshield wiper pump in my experience.

The pump either is frozen with water or is burnt out.

try and fill up the washer bottle with water for test and use it. if you hear the pump work keep using it till you see where fluid is leaking out. my guess is a hose is broken and all the fluid is leaking out

Was it on a cold day below 32 deg. F? If it was, could you verify that the proper season windshield wiper fluid was added? If not, then may have to wait until a warm day for it to unfreeze.

Do you hear the water pump whizzing or operating when you press the button to shoot water?

If not, then it's a possible bad pump, assuming that the fluid is not frozen.

Good luck on this repair.

Either the pump is bad, or the nozzles are clogged.
