body and interior Wiper Sweeping Issue

[billpatterson]

Hi there

 

 

I'm sure someone on the FAQ has experience with windshield wipers?  I am having an issue.  The wipers work...both normal and fast speed (via dash switch).  They turn off and park too.  The issue is that when they are first turned on, the initial sweep is downward a few inches (not up) then they come back upward and the cycle continues.  When turned off, they continue and park.  Thinking about how the wiping mechanism works (circular motion from motor to a repeating linear motion from wiper control arms to the wiper arms) it seems that the only adjustment is where one attaches the wiper arms on the windshield.  Normally, the wiping motion would begin with an upward sweep and finish with a downward sweep.  I think you can't really go wrong; However, I am obviously mistaken!  I did have the wiper control arms off (but not disassembled), the motor off, cleaned, lubricated, and everything reassembled and then installed into the car.  I have two theories,

 

1 - the wiper control arms are attached to the motor via a short arm.  Maybe this short arm is attached to the motor in the wiping cycle (of on, wipe up, wipe down, park, off) too early?

2 - the relay is pooched 

 

Does anyone know of any testing that can be done? Is there any info, pictures, video you may need to help diagnose the issue?

 

Would you mind taking a picture of your wiper system when parked/off specifically the short arm that connects the motor to the control arms?  These will show how much I may be off. 

 

I am thinking my approaches to further diagnose will be,

 

A - disconnect the short arm connecting the motor and the wiper control arms, turn on the wiper motor, turn off the motor, let it 'park', manually set the short motor arm/wiper control arms so the wipers will move up when the motor is turned on, reattached the short arm, test.  What do you think?  Or

B - try a new relay

 

Thanks!

This is the way to do it, or the way I did it. 

 

 

A - disconnect the short arm connecting the motor and the wiper control arms, turn on the wiper motor, turn off the motor, let it 'park', manually set the short motor arm/wiper control arms so the wipers will move up when the motor is turned on, reattached the short arm, test.

Thanks Andrew!

 

That makes sense to me. 

I will post the results.

Hi there

 

Solved.  

 

I disconnected the short arm from the motor, cycled the wiper motor, then manually adjusted the short arm just at the point when the wipers sweep upwards, and tightened it down.  It took a few tries but VOILA.  I really like easy fixes!
