I picked up an 09 IS250 a couple of weeks ago and finally drove it in the rain for the first time yesterday. I had the wipers on auto and noticed they were not turning on even though it was consistently raining. Only the manual (single wipe), low speed, and high speed worked. The auto never clicked on so I had no type of intermittent setting.
Out of frustration I tapped the rain sensor and then boom, it turns on. Worked for a few seconds then stopped. Pushed on it again, same result, worked for a few seconds, then stopped.
When I got home I took it off the mount and saw this:
Looks like whatever previous adhesive that was on it has now solidified into this hard plastic mess.
Looking for some suggestions on my next step. I saw a thread where someone suggested a gel pad, but not sure how much that may help since this is what's below it.
It's not a must have feature to me, but it'd be nice to have.
I watched that video earlier as well. His has that glass bump up slightly, but mine is (relatively) flush. Not sure what happened to mine, but that could explain why it seems to work when I push it against the windshield.
Dealer said gel pad should fix it so I just bought one off eBay and will give it a shot. I do have a replacement windshield so it could be a combination of both.Hopefully this will do the trick.
I loathe the rain sensing wipers. I am OCD about wiper speed and they always move waaay too fast.
My complaint is that the sensitivity control does so little I often wonder if it is even connected to anything. In a light drizzle, the automatic wipers sweep far too frequently, regardless of how I position it.
I'm not a huge fan of auto wipers either, but there is no way to disable it and go back to regular intermittent wipers. Unless someone can find the setting in Techstream those of us with rain sensing wipers are stuck with it.
I thought they were the coolest option when I bought the car. They are a pain in the a$$. If you live where it snows you will know what I mean. Never have the right speed.
I had auto wipers on my old Fusion, but you're 100% correct, they just never felt 'right'. Always just off speed-wise. Problem is, there is no way to turn it off on this car.
Yeah I tried that first after reading that thread the other day. Unfortunately it didn't work and I confirmed with service manage at the dealership by me that there is no way to disable it and go back to intermittent. Either all or nothing.
Gel pad should be delivered by Monday so we'll see how things go. I bought Rain X too so hopefully the next time it rains it won't be such a PITA.
