It sounds like the wiper parking position relay has failed. You see, when you turn on the wiper a series of relays on the actuator side are energized and cause the wiper motor to turn on and move the mono-wiper through its arc.

When it reaches the maximum extent of its travel, the wiper circuitry then reverses the arms direction and it swings back. This goes on until you turn off the wipers by turning off the ignition key or turning off the power switch.

When you turn off the wipers, the parking circuitry is activated. The central feature of this part of the wiper circuitry is the parking position relay. As the wiper begins to de-energize the parking position relay is activated. The position relay ensures that the wiper returns gently to the same position each time you turn off the wipers.

If the parking position relay weren't there, the wipers would park wherever they stopped on the windshield. However, the relay circuitry charges when you hit the off button and ensures that the wiper arm sweeps down to the same spot each time. If it does not activate, the wiper arm stops as soon as you turn off the power, as noted. This means that the wiper might, one time, stop in the center of the windshield or it might stop all the way to the left of right.

Aside from its complete failure, manufacturers build in telltales that indicate when the circuit is about to go. One of them is the wiper blade's parked position. Normally, the position relay ensures that the de-energized wiper circuit settles gently to the bottom of the windshield, as noted. However, if the position relay is failing most manufacturers have it park some distance from the bottom of the windshield to give you a head's up that the relay is on its way out.

Since the wiper circuits are fairly involved, it is best to leave it to a trained professional to do the work. However, if you feel you have the expertise to do it, your first step is to obtain the serviced manual for your vehicle. The service manual will give you the step-by-step repair procedure.

Since all parts of the wiper circuitry are related be careful, if you are repairing it yourself, that you replace each component according to the instructions as you might damage something else inadvertently.

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.

Fix monowiper park position on mercedes c 200 class


Does the wiper sweep past the park correct park position before parking or does it just never go low enough. If it doesn't go low enough, simply loosen the wiper arm from the transmission and lower the wiper arm to the correct park position. If it sweeps past the park position you need to disconnect the motor from the transmission when the motor is in the park position. The move the transmission to the park position and reattach it to the motor.

My lights and central lock are no longer working in my 2003 Dodge Dakota. How do I fix it?


Hi you need a new CTM (central time module)
Here is the location
when your siting in the truck it is behimd the panel next to your left foot 3 wire plugs and 4 screws remove it



80bcf9db.gif spacer.gif spacer.gif View Full Image spacer.gif 1 - CENTRAL TIMER MODULE 2 - COWL SIDE INNER PANEL 3 - SCREW (3) 4 - HEADLAMP & DASH WIRE HARNESS CONNECTOR 5 - INSTRUMENT PANEL AND BODY WIRE HARNESS CONNECTORS
DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version (Central Timer Module). Whichever version of the CTM the vehicle is equipped with, it is concealed behind the trim on the left cowl side inner panel below the instrument panel, where it is secured with three screws. The CTM is enclosed in a molded plastic housing with three integral external connector receptacles that connect it to the vehicle electrical system through one take out and connector of the body wire harness, and two take outs and connectors of the instrument panel wire harness. The base version of the CTM is used on base models of this vehicle. These base models are not equipped with the optional power lock system, the Remote Keyless Entry (RKE) system, the Vehicle Theft Security System (VTSS), or the remote radio controls. The high-line version of the CTM is used on high-line vehicles that are equipped with one or more of those options not found on base models.
The CTM utilizes integrated circuitry and information carried on the Programmable Communications Interface (PCI) data bus network along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal circuitry and programming of the CTM allow it to supply the vehicle occupants with audible and visual information, and to control and integrate many electronic functions and features of the vehicle through both hard wired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the PCI data bus.
The features that the CTM supports or controls include the following:
  • Automatic Door Lock - The high-line CTM provides an automatic door lock feature (also known as rolling door locks). This is a programmable feature.
  • Battery Protection - The CTM provides a battery saver feature that performs timed load shedding whenever courtesy, reading, visor vanity, center console, glove box, cargo lamps, or any exterior lamps are left on with the ignition switch in the Off position.
  • Central Locking - The high-line CTM on vehicles equipped with the optional Vehicle Theft Security System (VTSS) includes a central locking/unlocking feature.
  • Chimes - All versions of the CTM provide chime service and beep request service through an integral chime tone generator.
  • Door Lock Inhibit - The high-line CTM provides a power door lock inhibit feature.
  • Enhanced Accident Response - The high-line CTM provides an optional enhanced accident response feature. This is a programmable feature.
  • Exterior Light Features - The CTM provides control of park lamps, fog lamps, and headlamps. This includes support for optical horn (also known as flash-to-pass), headlamp time delay, cargo lamps, daytime running lamps (DRL - Canada only), and battery saver features.
  • Interior Light Features - The CTM provides control of courtesy lamps and dome lamps. This includes support for a timed illuminated entry with fade-to-off, interior lighting delay, courtesy illumination defeat, and battery saver features.
  • Intermittent Wipe Control - The CTM provides control of the intermittent wipe delay, and wipe-after-wash features for the wiper and washer system.
  • Panic Mode - The high-line CTM provides support for the optional RKE system panic mode including horn chirp, headlamp flash, and park lamp flash features.
  • Power Lock Control - The high-line CTM provides the optional power lock system features, including support for the automatic door lock and door lock inhibit modes.
  • Programmable Features - The CTM provides support for certain programmable features.
  • Remote Keyless Entry - The high-line CTM provides the optional Remote Keyless Entry (RKE) system features, including support for the RKE Lock (with optional horn chirp and park lamps flash), Unlock (with optional park lamps flash), Panic, and illuminated entry modes, as well as the ability to be programmed to recognize up to four RKE transmitters. The RKE horn chirp, park lamps flash features are programmable. On quad cab models only, a driver-door-only unlock or unlock-all-doors feature is also programmable.
  • Remote Radio Switch Interface - The high-line CTM monitors and transmits the status of the optional remote radio switches on the steering wheel.
  • Speed Sensitive Intermittent Wipe Control - The CTM provides a speed sensitive intermittent wipe feature.
  • Vehicle Theft Security System - The high-line CTM provides control of the optional Vehicle Theft Security System (VTSS) features, including support for the central locking/unlocking mode and control of the Security indicator in the instrument cluster.
Hard wired circuitry connects the CTM to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the CTM through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
All versions of the CTM for this model are serviced only as a complete unit. Many of the electronic features in the vehicle controlled or supported by the CTM are programmable using the DRBIII® scan tool. In addition, the CTM software is Flash compatible, which means it can be reprogrammed using Flash reprogramming procedures. However, if any of the CTM hardware components are damaged or faulty, the entire CTM unit must be replaced. The hard wired inputs or outputs of all CTM versions can be diagnosed using conventional diagnostic tools and methods; however, for diagnosis of the CTM or the PCI data bus, the use of a DRBIII® scan tool is required. Refer to the appropriate diagnostic information.

Wipers work fine until it rains then intermitient setting stops


This appears to be wear and tear of the Interval Timer Relay, for the Intermittent wipe cycle.

Wipers won't stop wiping.


Sounds like your intermittent wiper circuit is defective. Normally the intermittent feature is engaged by one of the functions on the multi-function switch (usually on the steering column). The circuit of the intermittent wiper periodically activates a relay that closes across the "Wiper On" switch. Your intermittent wiper circuit is likely defective and holding its relay closed (or the relay is stuck closed), thereby keeping the wipers on. Note: The wiper motor has an internal switch that opens when the wipers are in the park position and that is designerd to stop the wipers in the park position. When you turn on the wipers (or the intermittent relay is closed), the motor's internal switch is shunted such that the wiper does not stop at the park point of the cycle.

Wipers do not work in intermittent position. They do work in low and high speeds but do not automatically return to the park position. They stop wherever you turn the switch off.


i belive that your wiper switch has gone out on the intermittent side. this is a very common problem.
I hope this helps you
Thanks
