My rain sensing wiper is not sensing rain. Anyone know where to begin? Anyone has a fuse chart? It functions fine when I switch to constant speed but the intermittent speed 1 and 2 will not function. Any help will be appreciated.

Car still under warranty?

It's not likely the fuse. In order of common failures, it's normally the light sensor, then the controller, then rarely the glass (very rarely, but it happens). Have the car scanned, see what faults are present in the system. It won't necessarily show you a warning message if the rain-sense is disabled for whatever reason, but there can be fault codes.

Yes, it's still under warranty. I guess I'll make an appointment soon. Thanks

There are quite a few causes for the rain sensing to stop working. From dirty sensor lenses, through weak battery to sensor failure. Car needs to be read with star/ das.

Mysteriously the system is back working flawlessly now for two days. Whose to say, it might go out again

Sorry no help but I would like to have been an outspoken about my feelings on how beautiful car this is

Ah, not mystery. Your battery charged up. Next time when they malfunction hook up battery to a tender overnight and see if it solves the issue. If it does- you need a new battery.

If I leave mine in the rain sensing positing, the first notch, occasionaly they will do a phantom swiped for no reason in a nice sunny day. Dealer looked at it twice, said it's normal and the system isn't perfect. They told me to take it off standby and only turn them on when it starts to rain,.

Correct. Phantom swipes are common and not considered a problem. Sometimes the light reflects in such a fashion that triggers a swipe.

Of course dealer said something is wrong, and said they couldn't fix. Thanks for telling me this. I thought it was just me,.

Did Safelite recently replace your windshield? If so, you can start there because they're good at screwing them up.
