Fix my horn and washier fluid

The washer fuse should have power (battery voltage) while the ignition switch is in the RUN position. Verify both sides of the fuse have power. If the rear wash functions them it's not the fuse.

The switch signals the Body Control Module (BCM). The BCM energizes the front washer relay.

Input to BCM from switch is BCM connector C1,24 PK. Output from BCM to relay is connector C4 15 OG.

You need to verify continuity from the the switch to the BCM and from the BCM to the relay.

And you think we know what vehicle you own? Every vehicle is wired differently. Tell us the vehicle and then we can help

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 .

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper PCB relay
• Wiper high PCB relay
• Windshield wiper motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR fuse 25 A
• WSW fuse 10 A
This is more then likely not a fuse issue !!!!!!!
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !

Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.

Hood light on ????? hood ajar light ! Could be the switch . But without testing this would be a guess . Do you know how to test automotive electrical circuit's ? Do you know anything about automotive electronic's ? BCM - body control modules ( computer ) The first diagnostic procedure would be to hook up a factory or a professional scanner an check for DTC'S - diagnostic trouble code's in the BCM .

Your best bet , take your vehicle to a qualified repair shop. Nothing you can do without knowledge an proper diagnostic equipment .

will be 2 different problem check fuses and relays for both find and test horn its shelf

The rear windshield washer fluid for the rear window uses the same as the front. if it is like a '99 Explorer, it has one pump that has reversing current controlled by two relays . Access the relay box by removing air cleaner top and hose near right front corner. The front and rear washer relays are the two near the rear of the box. One of the two is sticking or has corroded terminals. You can use the horn or a/c relay from the relay and fuse box near the battery.Good luck and hope this helps.

If you jumper from the positive terminal on the batt to the horn and it doesnt sound off the horn is bad. But i would check the wiring to it make sure its connected and if there is a good fuse in place. If that checks good find the relay and make sure the relay it good.

The windshield washer pump is part of the windshield wash reservior.
There is an electrical connector located on the bottom of the reservior.
That is the pump .
If the pump is not in the reservior. I would just trace the washer fluid lines from the sprayer on the vehicle back to the pump. The lines just might lead back to the reservior for the windshield wash solution. Then you will have confirmed the pump is in the reservior.

You may have to get a new reservior. The pump might not be seperate item, I am not 100% sure on that.

I also would double check the fuses and any relays related to the washer pump.

Finally, I would check the washer switch if you replace the pump and still is not working .

Good luck

Before you go to the relay--see if you can scrub the fuse holders clean (for the horn and wipers). Remove the ceramic fuses, and take a stiff bristled brush and some rubbing alcohol to the contact surfaces. Vehicles I used to restore (from the South) that had been sitting a while had green oxidation on the fuse contacts that would cause intermittent opens on the circuit.
