    sounds like the wiper relay has failed.

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.

remove wiper arms and then you can raise the hood to remove screws that hold down the vent panel.
now carefully remove vent panel.

SOURCE: Wipers will not park on 93 ford crown victoria

Hmmmm... if you replaced the motor you must have cleaned the area housing the arm mechanism. I had the same problem and found the problem to be in the arm assembly box on the firewall. Under the hood, triangular shaped box with snap on top was full of dirt, leaves and pine needles... I removed all the **** & my wipers now park as they should!!

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 ?

Where is the wiper relay


A wiring diagram doesn't show a relay, just a 25 amp fuse in fuse panel under driver's side of dash. Intermittent working is usually from a loose or poor or corroded connection, or the switch is old and tired, or the motor is old and tired.
Here is one way to check, if you have a test light: when the wipers are not working with wiper switch on high, and key is on, pull off the connector to the wiper/washer motor module (in the engine bay, on the firewall) and check if the purple wire has power. If it does, you probably need to replace the module. Inside the module is a park relay switch (to return wipers to down position when turned off) and a circuit breaker between the motor and ground.
If the purple wire does not have power when key is on and wipers on high, the connection is lost between the switch and the module, or the switch may be malfunctioning. The switch has 5 wires, white wire from 25 amp fuse (power in to switch), a pink wire (for the washer motor), a purple wire (high speed wipers), a dark green wire (low speed wipers), and a gray wire (for the park relay switch inside the wiper/washer motor module). If you see a yellow wire also at the module, that is part of the low speed wiper circuit (the dark green wire) coming from the park relay switch and then to the motor.
Good luck. Post back if further questions, or need more help.

Front Wipers - not working


If you can move the wiper blades by hand, you probably broke-stripped the gear in the wiper motor.

Wipers wont go off


When you turn off the switch, there is a second switch in the wiper motor that continues to run the wipers until they are parked. If the window where that switch does not keep the wipers running is too narrow, the momentum of the motor turning will carry the wipers past the end of that window—they will continue until they are not-quite-parked. But not-quite-parked, in an absolute sense, is not parked at all, and that switch will reestablish contact, running the wipers to try to get them to the parked position.

Once there, the overrun happens again, and the cycle repeats.

Beyond that, if that switch gets stuck it will keep running the wipers, parked or not.

Sometimes the wiper motor can be easily accessed, opened up, and that switch can be serviced and properly adjusted. Sometimes the motor needs to be replaced.

Find the connector that runs the wipers, and disconnect it while the wipers are running. The blades will stop where they are.

intermittently, and briefly, reconnect the wipers trying to get them to move only 5 or 10 degrees at a time. This will avoid the motor get up a head of steam. If the wipers stop responding to this once they are parked, the window that the switch considers "parked" is too narrow. If they just keep responding to the application of power, even when they are really in the parked condition, then the switch has arced shut.

My windshield wipers wont turn on


Check the voltage at the wiper motor,with a test light,when turning on the wipers,one og the wires should light up,one of the wires will be lighting the test light all the time with the switch off.If the wire lights up,then replace the wiper motor,that is the wire that lights up only if the wipers are turned on,then replace the wiper motor,if there is not a wire that lights the test light check the fuse,if it is o k,then replace the wiper switch.

I went to use my wipers on my jeep and they wont turn on now i replaced the fuse but nothing


The wiper motor is burned out or the commutator in the motor is worn,

With the wiper switch in the OFF position, manually grab both wiper arms and move the wipers from their "parked" position.
Now turn wiper switch ON.

They may work from now on; if not, then the wiper motor needs replacement.

By the way, was the fuse blown?? (It won't change the answer).

Hope this helps...

Front wipers don't work


Winshield wipers inoperative in all switch positions:

Does your windshield washer work? Check circuit breaker in fuse panel. If it is good then you may have either a bad wiper motor or switch. If you have a volt meter check the white wire (going off 93 wiring color code) on wiper motor connector with switch in low to see if you have 12 volts. If you have 12 volts then you may have a bad wiper motor. If you don't then you may have a bad switch. Hope this helps.

Wipers wont work


1.  Turn on your wipers and pop your hood.   2.  If you hear you wiper motor, then you do not need to check your fuses. 3.  If your wiper arms are moving freely, then your linkage from the wiper arms to the motor is disconnected and possibly broken.   4.  If the problem is electrical, do the following:      1.  Check the fuse, and check for power at the fuse.      2.  Check the wiper motor for ground. For a complete circuit, you need power going in and ground               coming out.  Check electrical connections for corrosion or poor connections.       3.  Get a wiring schematic and trace power to the wiper motor starting at the fuse box in the                       following order:           Fuse box           wiper switch           wiper motor      4.  In the rarest of cases a wiper motor or wiper switch is at fault.  I do not recommend replacing                 anything unless you have proof that the part is faulty. (ie. power going into the switch but nothing           coming out.)
