Washer fluid pump not working

Good afternoon,

The power comes from the wiper motor. The switch on the stalk sends a signal to the motor and then off to the pump.

Do you have a voltmeter to do some checks? This guide can help

I attached a wiring diagram for you to view and when you are ready, we can do some checks. Check out the images (below).

I do have a volt meter. Thanks

Okay, go to the wiper motor. The gray/brown wire should have voltage with the switch commanding washer. Verify that voltage.

I will try to do that when I get home from work. Thank you.

You are welcome.

Always glad to help.

Hello, I checked the wires to the wiper motor, there is no Gray/Brown wire in the bundle. Is the diagram for a 2006 Ford Explorer XLT?

Yes, it is.

It is located t pin 12 on the wiper motor itself. Clean off the wires as they may have dirt on them from all the years.

Roy

Sorry for the late reply, the gray/brown wire has 11 volts when I turn on the key, and the voltage didn't change when I pressed the washer switch.

It should have 0 volts until you push the switch.

It sounds like you need a multifunction switch. You need to remove a couple screws for the clam shell around the column. Then remove the 2 halfs.

Once you do that, there are 2 screws that hold the switch to the column. Easy removal. There should be 2 wire connectors you have to loosen as well.

Removal and Installation

CAUTION: Do not remove the ignition lock cylinder and the ignition switch at the same time or damage to the column can result.

1. Disconnect the battery ground cable.

2. Remove the 2 screws and the steering column opening cover.
3. Remove the 3 screws and the upper and lower steering column shroud.
4. Disconnect the multi-function switch electrical connector.
5. Remove the 2 multi-function switch screws and the multi-function switch.
To install, tighten to 3 Nm (27 inch lbs.).

6. To install, reverse the removal procedure.

I must be testing the wrong wire then. I think I must have been testing a wire that turned on accessories or something. I'll retest once I have someone who can help me press the switch. I already bought and installed a new multi-function switch two days ago, and the problem persists. Hmm

You need to test the wire I highlighted in the diagram. If it is hot without pressing the switch, the switch is bad, new or not.

Roy

I want to make sure I test the correct wire. It's still Gray/Brown, right? And where should I be testing it? And I keep everything plugged in and the key on?

I actually have the wiper motor disconnected right now if it's easier to test the voltage this way.

You can check it disconnected, yes.

Test it for voltage. There should be no voltage unless the washer button is pushed.

Roy

Can you please confirm this is the wire? I've also included where I'm testing it in relation to the wiper motor.

You said you disconnected the plug at the wiper motor. If you did, you check it right there at the connector, not back in the harness.

Roy

I tested at the harness in the first picture. It was 0V and did not change when pressing the wash switch. However, I plugged it in and tested it at the harness as in the second and third pic. It was 10.8V when not pressing the wash switch and 0V when pressing the wash switch. I'm trying to get a video.

Okay, then the switch is a ground.

Hook the connector back up and then test the wire to the pump. Check for voltage when the switch is pressed.

Roy

Where would I test that? Is it the blue/white or gray/orange in your diagram? Do I go to the washer pump motor itself to test it or at the wiper motor?

You could go right to the pump or the blue/white wire at the connector. It should have voltage with the switch commanding washers. Do this with the connector connected to the wiper motor.
