Which fuse controls front windshield wiper pump

Do the wipers work ? Fuse for wipers is same as washer pump .
Principles of Operation
The wiper motors receive inputs from the following:
  • Multi-function switch
  • Powertrain control module (PCM)
  • Ignition switch
  • Smart junction box (SJB)
The following components are integrated in the wiper motors:
  • Windshield wiper motor module
  • High/low speed relay
  • Run/park relay
  • Washer pump relay
  • Park sense (Hall-effect sensor)
Washer System
The windshield washer and the rear window washer are activated by the internal wiper motor modules when it receives a ground from the multi-function switch between the washer inputs. Depending on the correct ground, the internal wiper motor modules activate either the windshield washer or rear window washer relays (internal) by grounding the respective relay coil. When either module is activated, it connects voltage to the washer pump while the deactivated module provides ground to the washer pump. In this manner, voltage polarity is reversible to achieve directional change of the washer pump and washer fluid.
  • The washer pump is inoperative
  • Circuitry
  • Washer pump
  • Multi-function switch
  • Windshield wiper motor
  • Rear window wiper motor
  • Go To Pinpoint Test I .
Does your expedition have programmable/recall memory option for seats an mirrors ?
Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
On the Expedition Limited, the power fold exterior mirror option is controlled by the DSM. Before running a self-test or retrieving codes, the power fold switch must be inactive for at least 30 seconds.
This is a complex vehicle , electronics , control modules an serial data communication networks. You mite be better off taking it to the dealer or some other repair shop . There could be DTC'S - diagnostic trouble codes stored in the SJB - body control module !

Normal Operation During normal operation, when the front wiper wash is selected, the windshield wiper motor provides power to the washer pump through circuit CRW14 (BU/WH) and ground is provided to the washer pump through circuit CRW12 (GY/OG) and the rear wiper motor. If rear wiper wash is selected, the rear wiper motor provides power to the washer pump through circuit CRW12 (GY/OG) and ground is provided to the washer pump through circuit CRW14 (BU/WH) and the windshield wiper motor.
    Possible Causes
  • Multi-function switch
  • Open in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN), CRW20 (GY/YE), SBB49 (RD) or GD149 (BK/GY)
  • Short to ground in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN) or CRW20 (GY/YE)
  • Washer pump
  • Windshield wiper motor

2000 grand marquis driver's side windshield wiper lifts off windshield

Hello Steve,

From your post, "Finally had enough and stuffed a small block of wood between the driver's side bottom of the molded plastic linkage frame enough to lift the whole thing enough to put a moderate amount of pressure behind the wiper blade..", it sounds like this box is warped or somehow out of alignment. Is it possible for you to buy this box from a wrecking yard? Has you car ever been in a collision? If so the frame may have so un-repaired buckling resulting in the misalignment.

How to replace the wiper motor on a 1994 volkswagon golf

The wiper motor on a Volkswagen is an electric motor connected through a drive linkage to the wiper arms. Windshield wipers are an integral feature for operating a motor vehicle safely. If your wipers are not functioning, or seem to lack the speed or power they used to have, the wiper motor should be removed and replaced immediately

  • The wiper motor on a Volkswagen is located directly underneath the plastic cowl cover. The cowl cover is located directly below the windshield.

  • Begin by removing the wiper arms by prying off the covers at the base of the arms and removing the nuts that secure the arms to the drive shafts. Label the passenger and driver arms so they can be installed in the same positions. They are not interchangeable. Remove the rubber hood to cowl weather seal. Unscrew the plastic fasteners from the driver's side of the cowl cover, then remove this half of the cover. Remove the fasteners from the passenger's side cowl cover and remove this half of the cover. Disconnect the windshield wiper motor wiring harness by separating the plastic wiring connector. Remove the three bolts that secure the wiper motor to the vehicle's body. Pull the motor slightly away from the body, then remove the nut that connects the motor shaft to wiper linkage. Remove the motor.

  • Place the new wiper motor into position in the cowl and reconnect it to the wiper arm linkage. Then reinstall the three retaining bolts. Reconnect the plastic wiring connector to the wiper motor wiring harness. Place the cowl covers into position below the windshield and reinstall the plastic fasteners that retain them. Reinstall the rubber hood to the cowl weather seal. Reinstall the wiper arms in the same position you removed them from, along with the wiper arm retaining nuts and lower wiper arm covers. Turn the windshield wipers on and test for proper operation. If the wiper blades slap against the bodywork surrounding the windshield, loosen the nuts that connect the wiper arms to the shafts and adjust.

Driver's side windshield wiper goes past window frame. How can this be repaired?

It could be a relatively easy fix or it could take some effort. First, try repositioning the wiper. By flipping up the end cap of the wiper arm and backing off the set screw that holds it on the wiper motor post. Remember, what position it was in by placing a piece of tape on the windshield. Pull the wiper arm off by pulling it off in line ith the angle of the wiper motor post. Take a close look at the splines of both the wiper blade arm and wiper motor. If either is damaged you will have to replace that component. Estimate the amount of adjustment you need and reinstall the wiper blade arm that amount in relationship to the piece of tape. Tighten set screw and try it.
If it still does it but less then repeat the process until you get it adjusted correctly. If there was no change thing it could be the wiper motor and that takes some effort to replace.

All you need to do is to remove the wiper blades of the driver side and then switch on and off the wipe so that the other wiper is seen to work in correct position. Now switch off and in the parked condition, fit back the driver side wiper to the stem.
The wiper must now work
