I would suspect a short in the wiper switch or motor to be the cause. You can try tapping on the motor with the wipers running using a hammer to see if they will shut off. If so, wiper motor replacement will be required. You can also unplug the wiring harness from the switch. If they shut off, you will eliminate any shorts in the wiring from the switch to the motor. The switch would be the next item to change/test
There is a circuit inside of the wiper motor which activates a part called a derailer. When the wiper switch is turned to off, the contact points on the derailer cause the internal parts of the wiper motor to jump to a position inside the wiper motor which breaks the physical contact of the connection that allows the motor to spin. On its last cycle, the wiper blades go to their park position and the motor shuts down.
Its possible that the points are dirty or the ground is bad. Sometimes unbolting the mounting screws and retightening will re-establish the ground, especially if one has a wire showing.
I would pull the motor assembly again and cycle the wipers by hand to get the blade assembly back to park horizontal position then re install. This is common when replacing the motor that the nylon gear assembly in the motor was not in horizontal park position
take the motor loose from the car leave plugged into harness ground motor turn on switch and see if motor will rotate on its on if it does you have installed on wrong side of stops or 180 degrees out if it does not you will have to find out why no power is going to motor start with fuse and work your way to motor ,
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.
The problem is in the wiper motor assembly. Did you ever notice that when you switch the wipers off they always go back to the home position? This is due to a switch that keeps the wiper motor operating until the wipers are parked. In many older GM vehicles this is accomplished with a leaf type switch which opens when the wipers are in the correct position. when the dash switch is turned on this switched is bypassed keeping them on-when the wipers are turned off the motor continues to operate until this connection is broken.
Inside the wiper motor housing there is a nylon gear that drives a cam that cycles the leaf switch-most likely the gear has become damaged so it no longer drives the leaf switch allowing the switch to remain closed. A cheap fix is to disassemble the motor unit and piece of tape between the contacts. Although the wiper will not park properly they once again can be controlled by the dashboard switch.
In later vehicles the wiper position is located with an electronic sensor with a small PB board - the repair of this gizmo is beyond the scope of most shade tree mecahnics - so the solution is to replace the entire wiper motor assembly - unfortuneatly.
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:
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.)
I had the same problem. The problem is in the switch (wiper, turn signal, hi-beam, hazard switch - multi-function switch). The part number is S14349 from BWD. My wipers wouldn't turn off and sometimes headlights wouldn't turn on unless I held the hi-beam switch back for about 5 seconds. After I changed the multi-function switch, the wipers still came on twice, but have been fine since (about a month). I don't know if it helped, but after I changed the switch, I pulled the top cover off the wiper motor housing (under hood against firewall right in front of driver - you have to remove hood weather stripping on top of firewall), checked the electrical connection to motor and also pulled up on ground strap checking the make sure I had good contact with the grounding strap. After I checked all that, the wipers came on once by themselves but I could actually turn them off and they have been fine since (don't know if there was some type of memory that caused the wipers to come on after I changed the switch, but they have been fine since then). Hope this is helpful.
you can just search for Honda Civik Factory Service Manual online. Also I had a simliar issue with my 87 rx7 and I took apart the wiper motor and cleaned up all kinds of muck inside. Put it back together and it works fine now.
