My truck has a problem with wipers and the rain. When the wipers are on my truck will stall. It will start right back up and run fine for a given amount time and then repeat. I have had the same problem while trying to clean the windshield on a clear day by just hitting the spray and letting the wipers run their cycle. I had a good amount of rain-x on the windshield before in a heavy rain and had no problems unless I turn on the wipers. Any ideas?
