Weird issue with wipers

Recommended Posts

So I had my windshield replaced yesterday (2016 Edge SEL) and when I started the car this morning, the wipers came on (wiper handle was in the off position) and the passenger side wiper immediately fell off. I turned off the car and inspected the blade and saw the connector was broken. I figured the techs who replaced the windshield broke it somehow, so I replaced it. 

 

Once I put a new blade on the passengers side and turned on the car, the wipers came on again, and again the passenger side fell off. It didn't break this time, so I just put it back on. Turned the car on again, and same thing happened. Wipers are off, but they always come on for one cycle and the passengers side always falls off.

 

I'm at a loss here. I've never seen this behavior when changing blades before. I've got the connector reinforced with a cable tie to keep it from falling off, but that's obviously not a long term fix.

 

Any ideas as to what's going on? Are the wipers activating to adjust to correct position? Why would the blade keep falling off?

For the connector thing, I am not sure which connector you mean, but as for the wipers coming on for one cycle, I am guessing that when you are re-installing the passenger side you are positioning it above the driver side wiper, in this case, the wiper will do a single wipe to correct the positioning. The passenger side wiper should be at the bottom & the driver side on top. That is normal.

 

For the connector, if you mean where the wiper blade connects to the wiper arm, with OEM wiper arms, the left & right sides are not interchangeable, they have slightly different connectors & aero spoilers since they are installed on opposite sides. Maybe they were mixed.

Thanks for the response. Yeah, for the connector I was talking about the connection between the blade and arm.

 

Are you saying the arms might have been switched? Is there a way to tell which is left and which is right? I could see this possibility since the passenger side blade was at the bottom and still did the position correction cycle.

Found a diagram. The left and right arms are in the correct position.

Does do the cycle on every startup or only the 1st after re-connecting the wiper blade? Compare the connectors from the arm's side, maybe the passenger side's is also damaged.

 

What I had meant was regarding the wiper blades themselves. The OEMs are different, right & left, and the connectors should be slightly different to avoid installing them incorrectly.

 

If you are still facing the issue, maybe post a few photos of how they are installed, someone might have other suggestions.
