This can be due to failure of the wiper mechanism or the control circuit.

SOURCE: Windshield Wipers

Under the cowl (it is a plastic piece that the windshield wipers come out of) are the wiper arms that connect to the wiper motor. There are plastic parts that hold the wiper arms to the wiper motor. Lots of time these plastic parts dry out and break and the wiper arm will fall off the wiper motor. I would bet if you tried to move one of the wipers by hand both of them would move with little resistance. This would tell me that the wiper arms are disconnected from the wiper motor. The parts to fix this are easy to get. I know the motormite HELP line of parts used to have the plastic bushings to fix this problem.

hi from the uk to adjust n/side wiper arm ? if you look at where the wiper arm is fitted below screen you may have a cap/covering that conseals the nut that fastens the arm to the motor wiper spindle which has a milti spline for adjusting? remove nut and pull up the arm and reposition as to prevent hitting bottom of screen ?? however if your wiper arms are the type without this nut fastening ? then same principle as above for readjusting but you will have to raise the arm verticle and carefully prise the arm off spindle there is a tool for this job and makes it easier it is a wiper arm puller you may be able to borrow or purchase? they cost approx £11 in uk but can be used for multiple other jobs ? so try 1st method you may be lucky ? when you reposition arm tap it on firmly!when you are happy with position ? good luck !

SOURCE: windshield wipers make loud noise but dont move when turned on

Probably stripped the little splines where wiper arm attaches to pivot. Flip the cover up where arm attaches to pivot, and tighten nuts on there, but be careful not to go too far, its not hard to snap the pivot stud if you tighten too much. make sure wipers are off, in park position, and move arms to where they should be, then tighten. See if you still get loud noise after. If you do, somethings wrong under cowl, in the linkages or motor. You may be able to see something with flashlight or troublelight.

SOURCE: 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.

We recently had an icestorm now my windshield wipers make a loud noise and wont work


Hi,
If you turned the wipers ON while they were still frozen to the windshield you likely stripped the gears in the wiper's motor. They're likely only going 1/2 way because the wipers also got misaligned on the motor shaft, too.

You may get lucky and be able to REALIGN the wipers on the shaft.

Wipers stop in the middle of my wishield,will not park properly


Sorry , no adjustment .
Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper 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 wipers will park the next time the ignition is cycled to the ON position.

My windshield wipers wont work.


It Sounds Like, Either The Arms Are Loose ,If You Can Hear Something Moving Behind The Dash,
Or The Linkages Are Seized ,If The Motor Just Hums No Movement Heard,In Which Case Try Spraying Q 20 On The Linkage And Try Moving The Wiper Arms By Hand To Get It Going Again,
If Not The Motor May Just Be Burn;t Out.

2004 tundra windshield wipers don't move but motor runs


If both wiper arms move, the linkage between them probably is OK. What isn't OK is the connection between the arms and the motor. You will have to get access to the motor area to find out what needs repair

The windshield wipers to my Ford focus stopped working today. They worked for a little while & then stopped in the up position. You can hear the motor working but they don't move. You can move them...


Your wiper linkage has come off the wiper motor. To reconnect the linkage, first remove the wiped arms, the remove the wiped cowl. The wiper cowl bolts are located under the hood and screws through the spaces in the cowl. Reconnect linkage, reinstall cowl, reinstall wiped arms.

The windshield wiper does not run, but i can hear a humming when i turn it on. I was told that it may need some kind of module.


It sounds like you may have a broken drive from the electric motor or the linkage to the wiper arms have broken.. The only way to tell for sure is to strip out the wiper motor and the linkages..which can be a big job and can entail removal of several other parts first.. Try moving the wiper arms manually, with your hands.. If you can move the wiper arms across the screen then the linkages have broken and will need to be replaced as they are not a repairable item..

I have a 1992 dodge shadow.but the windshield wipers isn't working.I checked the motor is well,the terminal voltage is 12V,how can I continu to repair the 1992 dodge shadow's windshield wipers?


You posting is slightly confusing but I gather your windshield wipers stopped working.
The repair method is as follows;
) Check the fuse.
) Check the wiper motor. Turn the wipers on and listen for the hum of the motor.

If you hear the hum then the linkage has probably come loose. You will have to take the covers off
to get to the linkage for the wiper. You can either repair the parts, get salvage yard parts or replace with new part$.

If you do not hear the motor hum then you should verify electricity is getting to the motor. A simple
voltmeter can be used. If the motor is bad you can replace it. Call some auto supply stores for after-market motors or call salvage yards for parts.
