NO YOU DON'T LOOK IN YOUR OWNERS MANUEL UNDER FUSES OR GO TO A PARTS STORE AND BUY A REPAIR MANUEL FOR AROUND $9,95. OR LOOK IN YOUR ENGINE COMPARTMENT FOR A BLACK PLASTIC BOX/ALSO UNDER THE STEERING WHEEL BY THE WALL/ALSO SOME HAVE FUSES PANELS WHEN YOU OPEN THE DRIVERS DOOR ON THE SIDE OF THE DASH.

2005 ford escape wiper and washer has no power. cant hear it engage when on but was working a week ago. how can i troubleshoot it and find the fuse


Hi Justin , Do you know what a SJB - smart junction box is and where it is located on you escape ?
Windshield Wiper Operation
The smart junction box (SJB) supplies power to the multifunction switch from the SJB fuse 25 (20A) when the ignition switch is in the ON or ACC position. The multifunction switch supplies power to the windshield wiper motor for the HIGH or LOW/INTERMITTENT input, depending on the multifunction switch position selected. The SJB also supplies power directly to the windshield wiper motor from fuse 25 (20A) when the ignition switch is in the ON or ACC position for RUN/PARK operation. When the multifunction switch is in the LOW, HIGH, or INTERMITTENT position, power is supplied to the windshield wiper motor, which moves the wipers off the park position. Once the wipers are off the park position, an internal switch in the windshield wiper motor switches to the run/park position which directs power to the wiper switch then back to the wiper motor. This maintains power to the windshield wiper motor to complete the wipe cycle. When the cycle is complete, the internal switch in the windshield wiper motor switches back to the park position. If the multifunction switch is in the LOW or HIGH position, power is supplied from the multifunction switch and another wipe cycle starts. If the multifunction switch is in the INTERMITTENT position, the windshield wipers remain parked until the internal relay in the multifunction switch supplies power to the windshield wiper motor. The internal relay supplies power after a time delay that is determined by the 1 of 9 intermittent switch settings.

How do I find out if the wipers on my 2006 H3 Hummeris on a relay?


The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper micro relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIP/WASH 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper micro relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay switched output to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

Low Speed Operation
When the wiper switch is in the Low position, voltage is supplied through an internal resistor to the signal circuit. The body control module (BCM) monitors the windshield wiper switch signal 1 circuit, and energizes the wiper micro relay which will operate the windshield wiper motor. The wiper motor will operate at low speed, since the wiper 2 relay is de-energized. Low speed can also be commanded with a scan tool, by commanding Wiper Relay Cmd. ON and OFF. Refer to Scan Tool Output Controls .
High Speed Operation
In the High position, the windshield wiper/washer switch supplies voltage to both the wiper micro relay and wiper 2 relay coils. This energizes both relays and allows battery voltage from the wiper micro relay switched output to the switched input of the wiper 2 relay through its contacts and out the switched output of the wiper 2 relay to the high speed circuit of the windshield wiper motor. The windshield wiper motor will operate at high speed. During high speed wiper motor operation the wiper switch signal circuit is at the low speed signal voltage, and the body control module (BCM) supplies redundant voltage to the wiper relay via the wiper diode.

This info is out of hummer factory service manual !

Looking for the fuse for the wiper motor 2008 chevy impala


WPR fuse 25amp under hood fuse box .
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.

What fuse controls the washer fluid pump?


On some older cars the washer motor circuit is tied into the wiper circuit, so the large fuse or relay for the wipers also controls the washer motor.
Don't know about your car, but you could take the connector off your washer motor and check for power there, when someone holds the washer pump switch on, and key on.

None of my wipers work. We were driving in the rain, and both the from and back wipers just quit. I did not check the fuses because they are 2 seperate fuses.


Both the front and rear wipers have a couple things in common. They are both powered by the 'Wiper System Relay". This relay supplies the power to both the front and rear wiper fuses. I would check for power at both of the fuses. If there is no power, then there is a problem with the relay or the relay circuits. The relay and both of these fuses are located in the underhood fuse/relay box. Please note that there is a "Wiper System Relay" as well as "Front Wiper Relay" and "Rear Wiper Relay" Why??? I don't know...some engineer at Saturn worked out his job-security with this one, I guess...

Any way, the Wiper System Relay feeds both of the fuses which, in turn, feed the two other relays.
The primary side of this relay is controlled by the Ignition 2 circuit from the ignition switch, so the relay is energized any time the ignition switch is on. (sounds like a good way to overheat and burn up a relay to me...but who am I??? I am not an engineer, I just get paid to deal with their stupidity)

The secondary side of this relay gets its power directly from the battery...no fuses in between, just a fusiblelink. This link is not the problem because there would be a whole bunch of other stuff not working - including your engine computer.

If I were to take a guess, it would be the relay.

Let me know if this helps you. Take a moment to rate my solution this will let me, as well as other know.

Windshield wipers don't work.Fuse is good and motor is good.No power to motor. The tag to tell what relay is for what is missing. Was wondering if the wipers had a relay and which one it is.


Hello Firerocker.
If your washer motor works there is power in the circuit and ground.
The wiper motor housing needs to be grounded.
If neither one works check for power on the green wire leading into the motor. If nothing there your switch may be bad.
If there is power to the green wire then check for power on the gray wire on low wiper speed and power on purple on high speed.
Here is a diagram if you need it.

Hope this gets your wipers going again.
