How to realign wiper assembly (wipers dont end up down at end of cycle

If your wipers no longer end up at the bottom of the windshield due to snow or some type of resistance, there is very good probability the assembly has slipped at the bolt in the picture. What I needed to do is loosen the bolt, move the assembly, tighten, reintall, and test. Chances are it will take a few adjustments to get this exact.

If there was a better way to fix this, please feel free to chime in. With winter approaching, I am sure this will happen to a few.

See post later down for photo, the photo listed here is wrong.

The wipers also can be indexed on the stub that comes up through the cowl.

Also the wiper arms are different and I have seen them mixed up and the wrong sides before.

I need to do this. Mine are off by about 2 inches so they swipe down a tad first before going up.

Did you do this adjustment while the linkage is still installed? I was hoping to do so.... Hoping to reach in, loosen the bolt, move the scissors to the proper closed position, then tighten.

Will that be possible?

Linkage needs to come out to fix the home position.

Simply loosen them at the post, reposition and tighten. Have done mine a couple times over the years.

Clarification

If you are trying to do minimal adjustment, you can do that at the cowl (Very minimal). If the wipers slop, you are pulling out the assembly, or you are watching your wipers start down your hood as they start their cycle out of position if you jut adjust at cowl stub.

This is the correct way to fix as this is where the original slippage started.

I don't see why I cant reposition the scissors on that one nut while attached but I'll need to get in there to see. Mine is not a motor issue I don't believe. I think the scissors has just slipped out of place a bit, I hope.

I listed the wrong picture. The bolt you need to loosen is the one circled in greenish blue.

If your wipers move down before going up, the motor is not stopped in the right spot.

There is an adjustment for Home Position of the motor, and for the stopping location of the wipers. If the motor is in the right place, but the wipers are not, this is cured by removing the wiper arms and setting them where you want them.

If the motor is not in the right place, I'm not sure what you do to remedy this, but the first movement would be downward before sweeping up. Having said that, I'm not sure it's a problem that the wipers move down before they sweep up, as long as the downward movement does not cause the wipers to hit something.

When removing the wiper arms to put them on in a different location, you would want to raise the wipers off of the glass and have them do a full sweep just to confirm home position.

I need to look at it, but why couldnt it be that the scissors is not in the "full down" position at the point where the motor stops its turn. So adjusting the scissors to be in the "full down" position when the motor is stopped would do it. The assembly scissors around to create the back and forth of the wipers.

that is correct - if the wipers move down pror to up, motor is no aligned

It is not as simple as repositioning wipers. If there is a motor adjustment, please let me know. I fixed by loosening the bolt and repositioning the assembly.
