Wipers Do Their Own Thing

I've noticed the wiper speed adjustment doesn't always work. I think there's two ranges and within each there's half a dozen or so speed adjustments. These controls don't always work as they should....and it's usually that the wipers go faster than the setting. There doesn't seem to be any pattern ..and it happens often.

Anyone have this?

Probably the switch going bad. I have replaced both my steering column wiper stick and the turn signal stick. Both went bad on me and I have a 2009 and it barely had 50,000 miles on it. You can pick them up on eBay for like $20 or 30 I think. They are pretty easy to replace.

It could be the speed sensitive setting where if you are doing over 40mph(?) the wipers will wipe at a faster pace to "keep up" with the rain. I never knew about the car having it and thought my motor or whatever was messing up till someone said something and I experimented with it, going slow and than speeding up.

Mine seem to be all over the place as well. However, I tend to think that it's less malfunction and more because it isn't a very well engineered control.

It's like when pizza places try to make pizza better by being "creative." Pizza was fine on its own. It didn't need any improving.

On my 2009, it's 50mph. I guess it's just a setting that changes automatically when you hit that speed, they go faster. Which sucks because the lowest setting going over 50 is still too fast for drizzle. It may seem like they're going crazy (I know I felt like it when I first noticed) if you're stuck in like traffic on a 55mph zone and you're dancing around that 50 mark.

Keegs - any comments? Speed related or unrelated??

I checked my manual and there is an explanation of speed sensitive operation, but it does not list specific speeds or intervals of change. It essentially states that the BCM decreases the wiper delay as speed increases.

Yup I noticed that right away on my 2009 Cobalt. I thought it was a good attempt at engineering a feature so you wouldn't have to touch the the control as often.

just be happy you do not have auto wipers, they work ok if you do not clean your window with any cleaners but back when I had a couple of cars that did they would go crazy in auto mode because I use rain-x on on my windshield and it the film it puts down would mess with the sensor. I love rain x though, on the cobalt if I was doing over 35mph I would never have to use the wipers.
