Wipers wont stop
Ok I give up on searching as Ive read several threads and cant find anything exactly like my problem. Ive already cleaned out the circuit board but I didnt see any water anyways. Nor have I driven in the rain in a few weeks.
Well when I started my car a few days ago they started going at low speed and stayed on for several min and then started working like they should. Today they did the same thing and I ended up pulling the fuse I can turn them on high but thats the only option I can choose besides the low speed. Is there anything that would cause this besides water or the wiper switch going bad, could it be a ground or did something go bad in the motor?

Well, for this type of stuff, you need to reach out....can save you a lot of time and money. The windshield wiper switch controls the voltage to the motor assembly. Easiest thing to check, is voltage at the motor connector. With the wiper switch in the "off" position, you should only have voltage on pin B....if there is voltage on any other pin, you either have a bad switch....or 12 volts shorting somewhere.

Ok so I just went and checked and with it in the off position I have 12 volts at B and if Im not mistaken D which is grey then as I go up to the first position I get ~7 volts on what I assume is E according to the diagram with it on long delay which goes up to 12 on short while still getting 12 volts through B and D. Then on low I get 12 volts at B, D and E. On high I get 12 volts on E as well A read zero the entire time which I guess is the ground.

Looks like I just had a typo for the last one where it should have been C that I was getting 12 volts through with the switch was on high. SO i had 12 volts on B and D in the off position. Delay I got power on E ranging from 7 volts to 12. On low I got a fixed 12 on E then on High I got power on C.

1) A contact for the washer switch is stuck, allowing 12 volts to pin D
2) The left most switch in the schematic is shorted.

Ok so how do I go about figuring out which one is my problem and how can I fix/repair it.

1) Pull fuse #10
2) Wiper switch to off position
3) Measure the resistance between pin B and pin D of the motor connector
4) Measure the resistance between pin B and pin E of the motor connector
5) Measure the resistance between pin B and pin C of the motor connector

Everything is contained in the switch, so I can only see one more isloation point:
1) Pull fuse #10
2) Wiper switch to off position
3) Measure the resistance between pin B and pin D of the motor connector
4) Measure the resistance between pin B and pin E of the motor connector
5) Measure the resistance between pin B and pin C of the motor connector
1) Pull fuse #10
2) Wiper switch to off position
3) Measure the resistance between pin B and pin D of the motor connector
4) Measure the resistance between pin B and pin E of the motor connector
5) Measure the resistance between pin B and pin C of the motor connector

Ok. That suggest to me, that one of the contacts(internal to the switch) for the washer is shorted(stuck). So, you can try depressing the button rapidly, while the meter is connected between B & D, and see if it changes to open (or no resistance).

When you say button do you just mean to move the stalk down for the single swipe function or up to the delay?

Well if I have someone telling me how to do it then its easy, anyways does that mean I have to replace it or can I tear it apart and fix it?
