The parking pawl probably has a broken spring and is not working correctly. The pawl is a 1.25" long piece of metal external to the motor and is part of the Stack-O-Plates on the output shaft of the motor and to which the wiper push rods are attached. When you turn the wipers to "Off" the motor will reverse direction and the pawl will catch on a stationary tab that is part of the motor/wiper frame. This will hold the wipers in the down position while the motor continues to run and allow the parking Stack-O-Plates-Spring-Wrapped gizmo to do its magic which drags the wiper arms down into the extra low "parked" position. If the tiny spring that holds the pawl in the out position breaks then the pawl will not engage the stationary tab. The wipers will then continue swinging upward through half a swing at which point a cam/switch that is internal to the pulse board (the cover on the motor output gear (three T20 Torx screws to remove) will tell the motor to stop because it thinks the parking Stack-O-Plates gizmo has finished doing its job but instead the wiper arms will be stuck in the "Hello, I'm a dork" raised flag position.
WARNING: Use caution while working around the wiper mechanism. If the key is on and the wiper lever is set to "Intermediate" then the motor can start unexpectedly. If your fingers are down there in the wrong place, the mechanism has more than enough power to break bones and/or peal the skin right off of them. Don't be afraid, just be deliberate and methodical and always be aware if the motor/electronics are energized.
It is very easy to remove the motor/wiper assembly so do not hesitate to do so:
Remove the plastic covers off the wiper arm retaining nuts.
Remove the wiper arm nuts with a 13mm socket.
Twist and pull with your finger tips and finger nails at the base of the small rubber squirt tubing off the hard plastic squirt delivery tubes.
You may have to yard up and down on the wiper arms pretty hard to get them loose from their tapered shafts. Don't be a mindless gorilla but be brave and keep at it. They will come loose.
Remove the cowl cover by pulling or prying out the center of the six retaining push pins. Then lift the cowl cover up then out at a 45 degree angle. You will find the cover is a very tight fit between the right hand wiper shaft and the weatherstrip at the base of the windshield. Be brave and keep pulling and prying until it comes loose.
Reinstalling the cowl cover and getting the rubber weather strip over the cover is the hardest part of the whole job. Use putty knifes (slowly and carefully!) or a very small slender screwdriver. It took me half an hour just to do this part of the job that. ugh.
Remove the 3 bolts holding the wiper assembly.
Disconnect the electrical connector by squeezing the retaining tab that you cant see on the backside of the connector. You have to squeeze real hard.
Lift the wiper assembly out.
Remove the Stack-O-Plates assembly from the motor output shaft (T30 Torx) to access the pawl to put on a spring. I wrapped one and a half loops of spring around one protrusion on the end of the pawl and around one tab of the stationary clip that limits the swing of the pawl to hold it in the "swung out" position. The loop of spring applies very light pressure but that is all it needs. This will all make sense when you are looking at the pawl mechanism. I cut off one and a half loops from a spring like what you would find in a retractable ball point pen but bigger. Use what spring you can find even if it from a ball point pen. When the motor runs in the forward direction the pawl harmlessly swings out of the way as it passes by the stationary tab. Bend the stationary tab in or out as necessary so the pawl engages straight on to it. I will try and post pictures of all this.
Before remounting the whole Stack-O-Plates gizmo assembly you will need to set the motor into the correctly timed position. Plug the motor in, then turn the wipers to "Intermediate". When the motor stops then turn off the ignition switch or quickly disconnect the motor. The motor is now in the correct position. Remount the Stack-O-Plates so there is about 1/4" to 1" space between the pawl and the stationary tab. Tighten down the T30 Torx bolt (blue lock tight recommended) then test the unit to see if the pawl engages to the stationary tab and lets the parking Stack-O-Plates do all its parking gyrations before you remount the whole wiper assembly. When you are all done try not to wear out the wipers by constantly turning them on and off for the next few hours of driving just so you can marvel at your handy work. :O)
Buy the way, if you turn the wipers off and they just wiggle a little bit while the motor goes click-click-click-click trying to do its parking thing then you need to alter (slightly) the relationship between the cam/switch arm inside the pulse module (again, the cover on the motor output gear, three T20 Torx screws to remove). There are two switch/contact arms in the center of the pulse board. The one closest to the board that engages the plastic cam mounted to the board is the one you want to change slightly. The other free floating arm is driven by the cam on the big motor output gear and is the contact to let the electronics know the output gear has rotated half a turn and the wipers are now parked. I bent the one arm closest to the pulse board away from its cam just slightly so that only about 3/4 of the "hook" on the end of the arm (you will know what I mean when you look at it) is hitting the ramp on the cam (the cam spins clockwise). Verify that the electrical contact actually opens a bit when the arm is riding on the high part of the cam. You may have to adjust and verify a number of times to find that sweet spot where it runs reliably. It took me half an hour of fiddling. O_0
replace the wiper motor
Could be for many different reasons. Maybe the sensor for the normal position is defective. The wipers might need a position adjustment, usually can be done by a flat head screw driver.
The car wipers should not stay up but return to their original position. The wipers will stay up if the wiper motor, the wiper controller and the wiper linkage are faulty.
It sounds like the wiper motor is malfunctioning. If your camaro has intermitten wipers there is a control module built in the motor that controls the off position.
There is a problem with the parking linkage. TAke it to a garage.
The wiper motor has a switch inside of it. When they are turned off and the wipers go to the down position it trips the switch in the motor that tells the computer they are in the down position. If that switch in the motor is faulty, the wipers are repositioning until the switch is tripped to the off position. THE FIX.... Replace the wiper motor.
If wipers stay stright up went turned off, you needs new motor. There are two parts to the motor, one is working and the other is not. Had same problem. new motor fix it
The motor shaft and the wipers are'nt connected properly(the timing is off), just disconnect the wipers from the motor. Turn your car on and cycle the motor and it should be back at the home position. Pull your wipers back down and reconnect and all should be fine.Thats if you put in a new wipermotor. If not, maybe the wiper switch is bad.
remove wiper arms from vehicleturn wipers onthen turn wipers offshut off ignitionreplace wiper arms at the down positionthis should be the return position when ever u shut wipers off
The "park" signal on the wiper motor is off. The wipers should stay off their cradles about an inch or so. If the ignition key is turned off during an intermittent wipe, the blades may stay at some position on the windshield. They'll return as soon as the next cycle comes up after the ignition is turned on. If they do not behave this way, you likely have a bad wiper motor assembly, which has the control circuit that parks the blades.
Could be rusty connections between the motor and the wipers, but you should probably check the multi function switch on the steering column that you use to turn them on, they do get corroded or worn out often because of the tendency of the interior of the jeep to get damp or wet.
A bad pulse board or window wiper motor can cause your wipers to stay in the "up" position.
The windshield wipers are not automatic... the lever that controls the wipers have three positions and you will have to pull the lever down to the off position. The position below off is for mist. If you pull the lever to that position and let it go, the lever will go back to the off position.
If you remove the wiper motor cap you will see where the arm connects to the motor. If you spray electrical lube or white lithium grease on and under the arm and turn them on and off a few times so that the grease works itself in they will stop sticking ad rest where they are supposed to when in the off position.
The "park" switch inside the wiper motor assembly has failed.
If intermittent wiper won't work either, it is most likely a bad wiper motor. Had a dealer replace the wiper switch, but that did not fix either problem. After dealer replaced wiper motor, problems were resolved.
Wiper motors have an internal switch that keeps the wipers running after you turn them off. The switch stays active until the wipers get to the "PARK" position and if the drivers wiper switch is off, then the wiper motor is turned off internally. I suspect the internal switch has failed. Unfortunately the switch cannot be easily replaced. Fortunately, wiper motors are not terribly expensive.
You will need to remove the wiper arms from the gear, they are normally held on with a bolt under a cover, and reposition them at their proper starting point. They should work normally after that unless the gear is stripped from the frost seizing them. What happened is that they were stuck to the windscreen when you turned them on and the motor turned anyways causing them to slip out of position on the gear.
There is a way to reset the "breakaway swicth" on newer GM wiper motors Go to a qualified GM dealer mechanic and pay. Then stop trying to wipe ice, froxen wipers, and too much snow with your wipers. Use a brush first!
first remove wiper arms from vehicle next with ignition on, turn wipers on then off. the wiper motor will stop at the down position. replace wiper arms onto shaft ,in the correct down position where you want them. now with ignition on, try wipers again,to check if in the stop position you want them.
most likely need to replace wiper motor. they usually have the intermitnant electronic card inside the motor housing and do not usually sell it separate. changing the whole motor box should solve your problem.
Many vehicles have a "mist" feature that makes the wipers swipe one time upon startup to remove mist or fog. This normally can be turned off...check manual.
this also is happening to me right now, and 600 dollars later i still have windshield wipers that work perfectly unless in intermittent, in which case they pause upright... Remove the plastic that covers your wiper motor just below the windshield. On the wiper motor there is a small plate held on by screws, remove the plate. You will see two metal tabs, one of which appears bent. Bend it back and reassemble. The problem usually occurs when the wipers are held in place, by ice for instance, and the switch is turned on.
Turn the wipers off, pull the wiper arm off, and replace it in the correct down position.
why is it after I hooked up the linkage for my wipers the wipers stay in the upright position after I turn them off.
