Anyone ever have your wipers "chatter" as they go down? They go up fine, and if you have full power to them, but if they are on an intermidiate setting the chatter or studder on the way down?

You may want to try cleaning the blades. Mine were hopping a good bit after I had done 3 weekends in a row of off road. Wiping down the blades seems to have helped as a short term fix, but I'll probably need new wipers soon. I've had a good experience with RainX wipers.

I tried new blades, Rainx style. Didnt make a differance. They are acting like they are loosing voltage or some kind of intermintant problem. Has anyone had the wiper motor itself go bad?

I have this same issue with my wipers. When on full they work fine. Intermidant they will just stop on the way down. Some times they'll stop all the way up. Sometimes in the middle or just stutter all the way down. Its not the blades or the windshield. I am very anal about keeping a clean windshield and good blades. It seems like a bad switch or relay or something. Any info would be great.

There is a TSB and a recall on this. Chances are the recall has been done but it was basically a band-aid fix. Water gets into the motor assembly and corrodes and shorts out the circuit board. The fix was to place a piece of foam I believe over the hole that was allowing moisture in. The problem with this was the damage was already done in most cases and it was just a matter of time before issues like you describe start happening.

I have the same issue with my wipers. I replaced the blades, make sure the windshield is clean (as much as it can be!) and nothing seems to have helped.... I'm gonna have to check out that recall and see if it was done on my tb as i've only had it a year and have no clue how much the previous owner kept up with it.

Same issue here but only on the drivers side. I don't remember having the issue when I had my last blades on there. I replaced the old one's a few months back with the Rainx brand. I also use Rainx wiper wash and occasionally apply the RainX stuff to the windshield. I thought maybe it was too dry on the way back down. It drives me NUTS though! I tried swapping the left to the right but that didn't help either.

Its not the blades- The contact wheel inside the gearbox is covered with grease, and caused intermittant contact, which causes the stutter. I cleaned mine after reading about this here 3 years ago, and its been fine ever since.

Remove wiper motor assbly, and take cover off of gear houseing. You will see a wheel that is covered in grease- wipe the surface clean and reassemble. Pretty easy free fix. You might spend some time putzing to make sure wiper linkage is aligned if you don't mark it before you start.

FKNA drolds, you saved me 75 bucks. :cool:

Remove these screws using a T20 torx bit.



Pry the cover off. It will sound like stuff is cracking and breaking but it is only the adhesive that holds the case together.



Wipe contacts and contact surface clean and reassemble.





Done.

Hey man, on a side note about your issue, If it is indeed not mechanical. I used to have the rainX wiper blades on my old Saturn. I too treated the windshield with rainX untill one day I was reading the instructions and either the wiperblade packaging or the rainX bottle said not to combine the windshield treatment and the wiperblades on the same vehicle because both were silicone based and could cause chattering...

I don't know if the formulation is the same now ( it was 6 or 7 years ago) but that could be a cause too...

just thought I would throw that in...
