Today I was driving in the rain when out of nowhere my driver-side windshield wiper went all the way to the left hanging off the side of my truck, and would not do any thing once reset in place. The passenger-side wiper seems to work just fine; but if I start my wipers up, the passenger-side wiper will get caught on the driver-side wiper and basically get stuck or bend the driver-side wiper. I had to drive slow to the store and pick up some Rain-X just so I could see enough to make it home.Is there an easy fix I am overlooking, or is this gonna cost some money to get repaired? Any help would be awesome, I am no mechanic.
Remove the driver side windshield wiper (pry it up with a screwdriver while using rags to protect your paint). Look at the stud sticking out and see if it has splines (ribs) on it. If it does, look at the inside of the wiper arm connector and see if is rounded out (no splines). Replace the entire wiper arm if it is worn out (easy fix). If the stud is worn, you will need a mechanic to replace it.
You may be able to flip up the little cover on the wiper pivot, and tighten the little nut on the wiper arm. Point it where you want it first.
It won't be the motor as it operates both wipers through mechanical linkage. BFH may be right about the set screw but what I would try first is to remove the driver side wiper at the pivot, turn the wipers on then off so that they go to the p[arked position and then reinstall the drivers side wiper arm, making sure that it was installed the way it normally is when parked.
