How to disconnect ww pump inbonneville

Replacing parts just to replace them wont fix a bad wire or part. Better to use a voltmeter and ohn meter to check if your getting power to the wires. You may have a bad connection or bad switch on the column for the pumps. Without checking the circuits it will behard to tell what it is thats wrong. Find a wiring diagram and trace the wires and components.

Just replacing parts isn't the way to find the problem , viewing wiring diagrams an testing the electrical circuit with a DVOM - digital volt ohmmeter is . There are no relays involved . Do yourself a favor an take it to a qualified repair shop before you buy more parts that are not needed .

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 !

When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

The Wiper / Washer System consists of the following components:
?€¢
Windshield wiper / washer switch

?€¢
Windshield wiper system module / motor

?€¢
Windshield washer fluid pump

?€¢
Windshield washer fluid level switch

?€¢
Instrument panel cluster (IPC)

?€¢
ACC 15-amp fuse

?€¢
WSW 30-amp fuse

Is your wiper fluid level good?Look for leaks at pump,it's connected to container,also check your hoses leaving pump to windshield,could be loose or binding.

Can you hear the washer pump running when you operate the washer switch? The washer pump is in the bottom (side) of the washer fluid reservoir. You should hear it running. If not, you can disconnect the wire connector at the pump and use a test light to check to see if there is power and ground at the connector when you operate the switch. If there is power and ground, replace the washer pump motor. If there is no power or ground, you most likely have a bad washer control switch. (You have to replace the entire Multifunction Switch)

If you can hear the pump running, check for washer fluid pouring on the ground. If this is the case, you have a broken hose between the washer pump and the jets that spray on your windshield.

Also note that there is no way possible that your problem could be CAUSED by a fuse!
For more information on this subject, please review this article: Where's The Fuse?

1) Fluid resevoir is empty
2) Fluid is frozen
3) Washer fluid hose is disconnected, blocked or kinked
4) Washer switch is faulty
5) Washer pump motor is defective
6) Washer pump fuse is blown

One can get a repair kit that includes a new motor pump and wiring clips, or

one can get the original motor that plugs into the windshield wiper fluid reservoir.

2. Raise and safely support the vehicle.
3. Remove the right front wheel and splash shield.
4. Disconnect the electrical connectors from the pumps and detach the rear washer hose.
5. Place a drain pan under the reservoir if it contains fluid.
6. Disconnect the front washer hose at the wiper unit in the engine compartment. NOTE: The front hose will be removed with the reservoir.
   
7. Let the fluid drain from the reservoir.
8. Remove the mounting screws and the reservoir.

To Install:

1. Install the fluid reservoir with the mounting screws.

remove the hose from the wiper arm and see if when you push the washer button that the fluid comes out the hose,if it does the sprayer nozzel is plugged if not replace the pupm

Check your fuses
