There is a electric motor that pumps washer fluid . Located in the bottom of the washer fluid tank .
Wash Operation (Front and Rear Wipers)
The front and rear washer systems use the same windshield washer fluid pump. When either the front or rear wiper is in the washer position voltage will be supplied to one side of the windshield washer fluid pump (depending on whether it is front or rear), while the other side of the pump is grounded.
At this point, the windshield washer fluid pump sprays solvent onto the windshield. When the front or rear washer is activated, the BCM receives an input from the switch that is activated. The BCM will control the wipers while in the WASH mode. The BCM will control either the front wiper relay or the rear wiper relay to turn on the wipers. The windshield wipers operate at low speed for 3 swipes and returns to the park position.
When turning on the washers do you hear the motor run ? Have some one try it while you listen at the washer fluid tank ! These pump motors do go bad .
turn OFF the ignition.
Disconnect the harness electrical connector of the windshield washer fluid pump.
Connect a test lamp from the windshield washer pump control circuit to a good ground .
Turn ON the ignition, with the engine OFF.
Press the front washer switch.
Does the test lamp illuminate?
YES or NO !
On a lot of cars, that washer pump circuit is really a sub-circuit of the windshield wipers themselves. The wiper fuse is also the washer pump fuse, in other words.
Use a test light or a voltmeter. Pull off the electrical connector at the pump on the washer fluid tank. Have a helper turn the key on, then press for the washer pump to operate. Take your test light and clip the ground lead to the negative battery post. Touch the tester probe to the positive terminal to assure the light is bright, that the test light will work. Now probe the connector at the washer pump. One of them wires should light up the test light, or would show battery voltage with a voltmeter or multi-meter. If it has power when key is on and washer switch on, the motor is bad, or sometimes you have to go a little further and find a ground fault.
If there is no power on any wire at the pump connector, you will have to look at a wiring diagram to diagnose it. Find out just how the pump gets power.
If you are just talking about the windshield washer pump/motor that squirts water on the front windshield, there is no separate fuse for that pump. If you are talking about the front windshield wipers themselves then the fuse for that (including the washer pump) is located is the fuse panel inside the vehicle down below and to the left of the steering wheel. Below is a diagram of the fuse layout (first picture) and I marked the 10 amp fuse for the system. As I said if you are talking about the pump/squirter motor there is no separate fuse. Inside the wiper motor itself (located basically on the firewall on the drivers side) is an internal microprocessor as well as an internal relay for that pump. If the processor or the relay is bad, both are internal and the whole wiper motor assy. has to be replaced. It's one complete unit. There is a chance that the pump motor itself could be bad. In the second picture is a breakdown of the washer fluid reservoir. In order to get access at it which is where the washer pump motors are located the right front wheel and splash guard have to be removed. I have marked the 2 washer pump motors which are mounted on the reservoir. I cannot tell you which motor is which but the one for the front has 2 wires at the connector (a black & white wire and a black wire) The rear pump motor has a violet & light green wire and a black wire at its connector. That's how you can tell which one is which. You can test the motor by either pulling it out and applying direct power and ground to it to see if it engauges or while someone is engauging the washer inside the vehicle while you are down there, see if you are geting power at the black and white wire. Check that wire while it is disconnected and using a good separate ground. If you are getting power make sure the black wire is geting a good ground. If all is good (ground & power) than more than likely the pump motor is bad. If you have a power supply problem at the black & white wire than you are looking at most likely a bad wiper motor assy but check for an open power wire from the wiper motor to the pump motor. It's not quite as simple as it used to be. The wiper motor on your vehicle has like a mini computer in it. I'm gonna say the washer pump motor is bad which is the most common. Hope I was able to help and that I didn't get too technical on you but things are not like the old days with separate motors (wiper and washer).
no the front is not in power with rear they are seperate. check wire plug (connector) at pump,( i assume pump is mounted on or in reservoir ) with test light for power while a helper depresses the spray switch. check for a blown fuse, check switch, check wiring
