I recently found out that I am having problems with my wipers. I am able to turn them on, but when i tried to turn them off, they would stop in the middle of their cycle, instead of going all the way down. I kind of had to guess when to turn them off in time to make sure that they werer all the way down. Also, when I was trying to clean my windshield, there was a delay before my wipers came on. The fluid sprayed for a while before the wipers even started. Any ideas on what could be causing this, and how I could fix it. Thanks
