Wow, no year stated. or engine size... ouch.
bingo, its intermittant, and all are hard nuts to crank.
after all if its not broke,you can't fix it.
what i do is lay in traps.
first off this is a 12vdc power distribution failiure.
the wipers proved that. hard fact.
on my cars i have a voltmeter, i never drive cars with out one.
next time have head lights on, and see if they go dim or go out.
HL have there own , hot at all times circuit and must work at all times. if they dont fix that first. (vastly simple they are)
flashight simple (unless in canada with bs DRL mandated)

the problem is a bad connection, the only real question is who and where/
and in every case, a $10 voltmeter answers this question.
its really too bad you never posted the year, and id have sent you
the distribution drawing, making this so easy.


its been 3 weeks, i bet its long ago, fixed and no post back.
but here is my answer, and others will land here (google) and see
what to do.
use a voltmeter (DMM , in walfart, to right of fuses....)

SOURCE: 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

My 2007 h3 hummer starts and when i put in gear it dies and the wipers turn on, the wiper wont shut off for several minutes then car restarts after they stop car will restart can take several attempts


Your best bet , take it to a dealer . The wipers are controlled by the BCM - body control module .
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

Testing for DTC'S - diagnostic trouble code's should be the first step in diagnostic process . No part store can check code's in BCM.
You have no idea of the complexity of the electronic's on your vehicle.
Moving the ignition switch to the START position signals the body control module (BCM) that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the powertrain control module (PCM) requesting engine start. The BCM also energizes the RUN/CRANK RELAY. When the RUN/CRANK RELAY switch side closes, and the vehicle is in Park/Neutral or with the clutch fully depressed, if equipped, supply voltage is applied to the PCM CNTRL relay coil. The PCM verifies the transmission is in Park/Neutral or if the clutch is fully depressed, if equipped. The PCM will then ground the control circuit of the PCM CNTRL relay, closing the switch suppling voltage to the starter solenoid. On some vehicles the starter will continue to crank the engine with the key released until it starts, the crank command has timed out to prevent excessive heat build up in the starter circuitry or the PCM receives an engine run flag.

2007 Pontiac g6 wipers stay in upright position


Hey Derek , here is how the wipers park position is suppose to work !
Windshield wiper motor park operation is controlled by the body control module (BCM) using an input from the park switch within the wiper motor assembly. The BCM monitors the windshield wiper motor park switch circuit to determine if the windshield wiper blades are at the bottom of the glass. The circuit will be pulled to ground by the wiper motor park switch while the windshield wiper motor is operating. When the wiper switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the BCM will continue to operate the motor until the wipers reach the park position. If the ignition is turned OFF while the wipers are in mid-cycle, the wipers will stop immediately where they are. The BCM will park the wipers the next time the ignition is turned ON.
The wipers will not park when they are commanded ON and OFF with a scan tool. The BCM will park the wipers the next time the wiper switch is turned ON and OFF.
The BCM provides stall protection for the wiper motor by monitoring the park switch. If the park switch does not transition for 3 seconds while the wipers are operating, the BCM will assume that the wiper motor is stalled, and will de-energize the wiper relay until the wiper switch is cycled OFF and ON again.
Check for a voltage signal on the yellow wire at the wiper motor assembly , this is signal to the BCM ! If there is no signal you need to replace the windshield wiper motor assembly ? If there is a signal need to have Tech 2 scan tool hooked up to see if The BCM is the problem ! Relay #39 an #40 are the high an low wiper relays in the under hood fuse block ! Do you have a volt meter ,do you know how to do electrical testing ?

Monowiper works fine when in full wipe but when in intermittent wipe and park mode it stops 3 inches too high ??


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.

Windshield wipers will not park


Your problem is probably in the wiper transmission itself. There is a switch that tells what position to stop feeding power to the motor. But if that switch isn't working, the rest of the system does not know what to do, nor exactly when! However, if you have a good concept of timing, what you COULD do, is simply turn the wiper switch off the instant they are at the "lowest point" in their sweep cycle ... at a cost of NOTHING!

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.

Windows won't roll up and down and wipers stopped working at the same time. The blinkers stopped shortly at the same time but they are working again. We thought it was a fuse problem but the fuses seem to...


Do you know anything about automotive electronics ? The GEM - generic electronic control module is in charge of turning on the wipers an control the power windows . Would think this a fuse problem . Computer problem maybe , the first step in diagnosing a problem like this would be to hook up a factory or professional scanner an checking for DTC'S - diagnostic trouble codes . Don't think about replacing the GEM module ,if you don't know how to test it's electrical circuits an check for codes . Can set a number of codes !

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.

hi you have a short your favourite place to look is the wipers relay they are more likley to short than the switch and there cheaper if no joy remove your steering wheel cowls so you can get at the switch find out which wire feeds the relay to turn the wipers on see if its permenantly live when you turn the switch off if so replace switch if the switch works as it should and the relays ok then the motors faulty yates210456
