1993 Ford Taurus Wipers not parking where they should.

When the wipers are shut off, they should park at the bottom of the windshield. Just today they park at the top of the stroke.

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 ?

My 1995 ford tuarus windshield wipers park in the wrong place, otherwise they work. fine


This can often be an issue with the wiper stalk on the side of the steering column.

Take the wiper arms off at the wiper shafts Cycle the wipers and park normally. Refit the arms in the parked position. Make sure the nuts are tight or are fitted correctly

I recently changed my wiper motor in my 2003 Hyandai Accent. Now the windshield wipers will not stop at the bottom. When I turn thw wipers on, it goes donw first then up then back and stops in the middle...


Remove the linkage from the wiper motor. Turn the wipers on then off. This will set the motor in the park position. Move the wipers by hand to there normal off position. Reinstall the linkage onto the wiper motor. The wipers should now park or stop in the correct position.

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.

Windshield wiper doesn't work on the driver's side?


It sounds like the retaining nut has come loose. First cycle the wipers and shut off to put in the park position, Remove the cap at the base of the wiper arm there should be a nut. Position wiper to where it usually rests in the park position, and tighten nut. Try the wipers, if working replaced cap good to go. If it still doesn't move then quite likely that side arm has popped off the wiper transmission underneath the front cowl. Remove both wiper arms by taking off nuts and prying off, check underneath the cowl. If you find the arm popped off a ball stud reattach and try wipers (without installing cowl or wiper arms, just check to see if both sides swivel. If it pops off again its worn out and you will need a wiper transmission.

1990 Ford Taurus GL windshield wipers park in the wrong position


I have a 1996 Ford Taurus with a similar malfunction the intermittent wiper function is erratic, but the wipers park properly. I'm the original owner & this malfunction was in the car from the factory. I have a regular Ford Dealership manual & came to the conclusion that the Generic Electronic Module located behind the fuse panel is bad (computer glitch in programming) ! Ford Dealers want over $ 300.00 for a brand new module, I haven't checked with my local used auto parts recycler yet, but I know it will be less than the dealer price !

93 lumina van wiper motor starts but wont shut off


The routine (resistor) that shuts off the wipers and parks them correctly is in the wiper motor, not the switch. I assume your switch is good since you make no complaints about its movement. One thing to check before replacing wiper motor is to loosen the wiper arms, and let the motor park itself in what you feel is the bottom of windshield position. Now align the wipers and retighten.

If these get positioned wrong after, say, a frozen morning, this will affect parking of wipers since motor "park" is no longer in synch with wiper arm "park."

Otherwise, if wiring and positioning are correct, I recommend replacing the wiper motor itself.
