Re: 1998 dodge caravab
Your not in a cold enough climate for it to be frozen are you? Can you hear pump trying to work? "click, click, noise from it?
Did you try tapping pump with a screwdriver handle or similar,while someone pushes wash for you? If pump making any noise at all, try taking the small hoses off from pump, one at a time & see if anything squirting. If it squirts, you've got plugged hoses or nozzles, try blowing them out if that's the case.

High resistance, partially broken wire, corrosion or poor connection, something in that circuit...somewhere. Take a voltage reading at the pump's fuse for a starting place- if you have a good 12 volts there, the loss is from that point in the wire to the pump connector. The switch, the junction block. Look at the pump connector- is the wire connection good- and back from it at the wire where it may have got pulled or yanked hard, breaking some wire strands, or got exposed to heat and burned a bit, look for things like that. I hope you don't have to pull some wiring harness apart. That's tedious, easier to rewire it after a point. Good luck.
the wwasher pump is on the same fuse as the windshield wipers so if the wiper work than the fuse is fine.
Check for power at the washer pump on the red wire. It should have twelve volts any time the washer switch is pressed. Make sure the ground wire (black) is good. If there is power and the ground is good than the pump is bad.
If there is no power than the switch is bad or there is an open in the red wire from the switch to the pump. You should be able to find that red wire on the back of the switch if there is power there when you press the switch than the wire is open. If there is no power on that wire on the back of the switch than the switch is bad.
Your symptoms are typically that of a defective fuse. There are no relays for either the wipers or the washer pump and both operate off the same fuse. Check the fuse again and make sure that it is making good contact on both contacts. With the ignition on, check that you have 12 v + on one of the fuse contacts to earth, use a volt meter or a 12 volt bulb to check this. If you have power and the wipers are still inoperative you will have to start looking at wiring and the wiper/washer switch incoming power wire right from the fuse box.
The washer pump runs off the same fuse as the wipers. If the wipers are working the fuse is good.
What you can do is locate the washer pump in the washer fluid resevoir. You will need to remove some splash panels under the car to get at it. Unplug the connector. One wire should have 12 volts to it anytime the washer button is depressed. The other wire should be grounded all the time. If that checks out the washer pump is bad.
If you don't have power than I would check for power out of the wiper/washer switch. If there is no power there than the switch is bad. If there is power than there is a wiring issue in between the switch and the washer pump.
With the washer pump lugged in you can try to tap it while somebody turns on the washers. If it starts to work than replace it.
The plug you are referring to is probably the fuel tank pressure sender not the fuel pump. It would be plugged into a black sensor about 2 inches long pushed into a rubbergrommet on the fuel bung. The fuel pump connector would have more that 2 wires going to it. most likely a heavy purple wire would be the power to the pump. It has to have 12 volts to it to work. The sender may have 3 wires, 5 volts, ground, and sense. the pump connector would have 12 volts, ground and 5 volts for the fuel gauge sender down in the tank.
If the 12 volts is not there, check the fuel pump relay. it is usually up on the drivers side firewall.
With the key in the on position without starting the engine, you should have 12 volts to the pump for 3 seconds then it will click off. Without cranking the engine you should be able to locate the relay by the clicking sound.
There is also the obvious, like checking the fuel pump fuse.
check the fuse panel for weak or blown fuse in the wiper/washer circuit if that all checks ok then using a test light or volt meter then find the washer pump leads at the bottom of the washer pump itself and with the circuit activated make sure you have 12 volts going to it also check the ground wire to it to insure proper ground if voltage is present then remove the motor assembly from the washer housing and relace the motor
Check fuse first, then unplug the connector going into the washer tank and take a 12 volt tester and plug it into the hot side of the wire while attempting to wash your windows...does the tester come on. If the answer is yes, your pump has failed.
Go and invest in a 12 volt test light. They can be purchased at any parts store. Attach alligator clip of light to a good (any) ground. Have someone activate the washer pump while you pierce the wire with the ice pick end of the test light. One wire is the ground the other is the 12 volt feed to the pump. The ground wire will be black or brown. You might want to just check both wires. If voltage is present the pump motor is bad and will need to be replaced. If there is no voltage you have an open circuit between the fuse and pump motor. Run the test first and let me know what you find.
The washer fluid is usually on the same fuse as the wipers so, you probably wouldn't find anything there.
There is a little black pump that is usually in the bottom of your washer reservoir that goes out from time to time.
Disconnect the power wire to the pump and using a test light (and someone inside the car to push the wash button) connect the ground lead of the test light to the neg side of battery and then probe each connector of the wire while the button is being pushed. If you have power, then it is very likely that the pump is bad, if you don't have power, then you will have to trace out that wire and make sure that a little mouse hasn't used it for a nest.
