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.
There's a few things you might want to check. First, check to make sure the washer fluid reservoir is completely (assuming you hadn't already done that). After you are certain the reservoir is full, look for any possible leaks...either the reservoir or the hoses going from the tank to the windshield. If the tank and hoses are intact, turn on your windshield wipers...then try running the pump. If no washer fluid comes out, and for this you might need another person to assist you, try running the pump again...listening to make sure the pump is in fact running. If the pump does run but still no fluid comes out, inspect all of the hoses as well as all of the outlets where the fluid sprays the windshield...it is possible that the outlets may be plugged. Some common reasons for the outlets to be plugged...debris, dirt/mud, and/or wax (has anyone recently waxed your Freightliner?). Just to be sure, using a small needle or even a wire, ensure each outlet is cleared and not obstructed with anything. After that, try running the pump again. If no luck, try removing the hoses going from the tank to the windshield. Once removed, using something like a wire coat hanger, clear each hose for any possible obstruction. Reattach hoses and try running pump again. If still no luck, I would guess the problem might be located with the washer pump itself. Before opting to replace the pump, if you believe that is the problem and the pump just doesn't operate, check all fuses and inspect any/all wiring connections.
Try using a "Tooth-pic" or pin tool to clean out debris from the two spouts at the windshield. If these are clogged, and I've seen it happen hundreds of times, the washer fluid will go nowhere. It's like having your finger stuck inside a water hose......nothing will come out. Many people use water from a hose to fill the washer bottle and this water has contaminants that will clog the spout at the windshield. Also poorly made washer fluid will clog the line and thus nothing will come out. To free up the clog just use a tooth-pic to dislodge the debris. The best windshield washer fluid I could recommend to ease this problem would be a home-made batch of 40% Windex to 60% distilled water. God Luck!
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
sometimes there is, and sometimes there isnt, if there is one it will be on the bottom of your windshield washer tank.. sounds like they fed you a line of **** to me... and if they arent i would take it back and ask them why its doing it again, and why they didnt clean the tank out before... theres something else going on.. either a leak in one of the hoses, your low on fluid, or the pump is weak... i think they fed you a line.. hope this helps
Check the hoses running to the front windshield washer nozzles. If the hoses are good check the pump to see if it is working correctly. Remove one of the hoses from the spray nozzle and see if the pump is working. If it is then the spay nozzles are stopped up. Use a needle to clean them out. They can easily get plugged with wax. If the pump is not working then either the fuse is blown or the pump is defective.
