SOURCE: I HAVE A 2002 AVALON. THE INTERMITEN WIPER DOES

I was able to determine that the connector on the wiper motor was faulty. I believe it is a poor design for a connector. I gave a small twist to the thin prongs with needle nose plyers and this resolved what I think is a poor connector contact pressure problem.

The problem is a broken part in the module which is inside the wiper motor. As far as I know, the part is not available, and you must replace the entire wiper motor to repair the problem

SOURCE: windshield wipers work on "high"

Don't really know of the vehicle, but what I am use to is that this could be the switch Since the wipers do work that rules out the motor. But, there could be a fuse or relay that controls that part of the system?

Most likely its the relay. See if you can hear any faint click from the fusebox area.

The generic electronic module (GEM) responds to the windshield wiper control commands by interpreting inputs from the steering column multi-function switch. The speed dependent wipers will compensate for the extra moisture that accumulates on the windshield at higher speeds, except when the multi-function switch is in the INT 1 position. At higher speeds, the speed dependent feature shortens the delay between wipes when using the variable interval wipers. Delays will automatically adjust at speeds between 16 and 105 km/h (10 and 65 mph).
Testing should be done before replacing any parts . And if you don't know about (GEM) Control module controlled system's your best bet , take it to a qualified repair shop . The first place to start trouble shooting these systems is with a scan tool that can read GEM module codes .

My windsheild wipers stop in the up position on the delay setting but park all the way down when turned off. How do I fix this


You will need to diagnose this with a multi meter....on dark green terminal d at the wiper pulse board, with the wipers on any delay position, you should be reading .0005 Amps and 12 Volts and at the same time on the delay position one click below low(the fastest delay speed) you should be reading .0003Amps and 12V on terminal E gray wire, The purple wire (terminal C) should have 12V on high speed only. The yellow wire (terminal B) should have 12V when the key is on and the black wire (terminal A) should always be grounded....check all of that and we should be able to find your problem.
The Amperage should change on terminal E (the gray wire) with each position on the switch but the change will be very small. i.e. the first speed (longest delay) will read .000017 A, the second setting .00004 A and so on. Check that and let me know...(by the way, amps are checked in series with the connector so unplug it, place one probe in the connector and the other in the motor plug terminal. )

Usually the park switch inside the wiper motor is the fault.

98 monte carlo z34 sometimes wipers won't shut off. is this the turn signal lever or the wiper delay board?


Could be either one.
The wiper switch could be providing power, and there is a park switch in the motor that provides power until the wiper arms "park".
You may be able to disconnect the wiper switch to find out.
Chances are you'll need a wiring diagram to test the circuits.

Does any one know if a 1999 dodge ram 2500 has a wiper delay module on it. my wipers will not park.


if you changed your wiper motor and did not turn it on and let the motor return to park before installing blades,i would remove the blades ,turn on the wipers and then off and wait till they do park,then reinstall blades.

Wipers would not park, customer forced down wiper arm and broke off arm. Now no electric to wipers.


Before 1995 Ford interval wiper systems mainly consisted of a switch, the motor and the interval governor (also called the wiper control module or 'WCM'). The basic wiper systems just parked the wipers at the end of their travel at the base of the windshield and involved just one park switch.

The more complex systems not only stopped the wipers at the base of the windshield, but would actually recess them below the windshield to park them. This involved using two park switches to turn the wiper motor in a reverse direction. These were installed on the Crown Victoria, Grand Marquis, Town Car, Taurus and Sable.

The wiper switch (named 'Multi-Function Switch' on most models) had a common return or ground circuit and two input or signal circuits to the WCM. Basically, the switch was two modified potentiometers that varied the resistance to ground for the two signal circuits. When the wiper switch was placed in the low or high position, the WCM looked at only one of the circuits- the 'mode input' -and controlled the wiper motor accordingly. If the wiper switch was placed in any of the interval positions, the mode input told the WCM that the switch was in an interval position. The WCM then looked at the second input - the 'delay input' - and used it to determine the amount of delay between wipes.

1) To run the wipers on low or high speed, the WCM provided constant power to the wiper motor on the proper circuit to provide the requested speed. Dual park switch motors
1.1 The first park switch operated basically in the same way as the single switch systems.
1.2 The second park switch worked in the opposite manner- when the wipers were off the park position, the second switch provided a ground for the wiper motor. Power and ground were now provided by the park switches.
1.3 When the wipers needed to park, the polarity of the switches changed, and thus provided reversed voltage to drive the motor in the opposite direction.

2) To run the interval wipers, the WCM applied voltage to the wiper motor only momentarily to get the wipers off the parked position.
3) The electro-mechanical park switch made a circuit between the power feed in and the output to the WCM. Power was provided from the park switch through the WCM and back to the wiper motor.
4) When the wipers reached the park position, the park switch made a circuit between the ground and the output to the WCM, and the motor stopped running. The wiper motor and the wiper switch have remained much the same as the single park switch motors of the past.

The main difference is that the switch has become an input to the GEM instead of the WCM.
1) When the wiper switch is placed in the low or high position, the Run-Park relay is grounded by the GEM to provide constant voltage to the High-Low relay, which then provides voltage to the proper circuit of the wiper motor.
2) High-Low relay is in the low speed position unless grounded by the GEM.
3) The park switch not only feeds the Run-Park relay but is now also an input to the GEM. This tells the GEM when the wipers are in the parked position so it can de-energize the Run-Park relay.
4) When any of the interval positions are selected, the Run-Park relay is momentarily grounded to get the wipers off the parked position
5) The park switch then provides voltage to the other set of contacts in the Run-Park relay.
6) When the GEM de-energizes the Run- Park relay, voltage is still provided from the park switch to the High-Low relay and the wipers complete the stroke.

Delay wipers don't work.


Try making sure the connection is good.
If it is then you should try replacing the wiper switch.
