I have seen some topics on this but no answer to them. I am having a similar issue however it only seems to do this in the warmer months and in the colder months it does not does this. Wondering if it could be a faulty control module or what but when I start the truck the wipers swipe one time on start up and go back to normal. There is no rain sensors and the module is in the off position when it does this. Any knowledge of this would be greatly appreciated...
