Spastic Wipers - huh?
 
I've had my WK2 for a couple years and never noticed this condition before:

Highway driving, light mist mostly kicked-up by cars ahead of me. Wipers frantically switch between crazy-full-speed wiping and then slow-speed wiping, back and forth, over and over. Wiper switch was dialed to first detent, rain/mist conditions did not seem to change appreciably.

I realize the rain/windshield conditions dictate when wipers switch on and off, but I thought I needed to dial-in the wiper control the 3rd detent to get max-speed wiping.

This may be normal function, but seemed totally unfamiliar in my Jeep.

Thoughts?

Might be because they are speed sensitive at this setting.

Confused.

Even at constant highway speed this frequent variable action is a normal function?

My vote would be that this is normal especially at highway speeds. Windshield sensor is reading light dispersion caused by droplets which tend to spread out and/or merge together. It is one of those options that I can live without.

It happens from time to time on all vehicles with auto wipers--the sensor gets a bit confused.
As previously mentioned, this is one feature that I could live without. I can set my own variable wiper speed, thanks.:o

According to the 2014 manual this feature can be turned off in the EVIC. It also explains the sensitivity settings. Don't know about the '11, '12 & '13 model years.

I'll need to set the "Spasticity" setting = 1 :)

I could very well be wrong but I think the overall sensitivity depends on which variable setting (on the stalk) you have it on. I've noticed that if it's a bit heavier than misting but not really raining I will put it on the second variable detent and it seems to trigger the auto-wipers more often. Which of the vaiable settings on the stalk do you have it set at?

As far as the overall functionality of the auto-wipers, I like them. I've been on the highway where they would be running a normal speed for the conditions and then when I go by another vehicle they speed up because of the additional spray from the other vehicle and then they calm back down after I have passed.



*EDIT: Sorry I missed the part in your OP that mentioned what detent you were on...my bad
