sounds like they have been taking off and returned to the improper location. or at worst the splines in the arm at the end off the wiper or the shaft they are on is stripped.
you need to pull the plastic cap off the wiper arm base, remove the nut holding the arm to the splined shaft. then pull the arm off and turn the wipers on. if the little splined shaft is turning back and forth with the remaining wiper arm, then you have a bad wiper arm. the splines or serrations on the inside of the base get stripped and the little shaft cannot grip it to move it anymore. take your wiper arm to a local junkyard and have them find you a replacement which is not stripped. put it on in reverse order, if you have some loctite around this would be a good time to use it when you tighten the nut back down.
if the little shaft is not turning back and forth, then your wiper linkage or transmission is bad and this will most likely be a job you will want a shop to to. do not pry on the glass or use the window as a pry point to lift the arm off, it may need some gentle rocking to come loose but not prying.
open the hood and at the base of the wiper arm is a little balck cap, remove this cap and under it is a nut. this nut holds the wiper arm tight onto a spline. check to see if the nut has backed off or needs to be tightened. if not remove the nut and take off the wipers, the black cowel (at the bottom of the windshield) is held on with three plugs.(one in the middle and one on each end.) and one large plug below the passanger wiper blade. the wiper assembly and motor is under this cowel.
hope this helps
The windshield wiper linkage comes as an assembly. The assembly comes with the two rotating splines that the wiper arms attach to. you must remove wiper arms. Remove cowl trim and remove bolts that hold the pivot points to the body. The new linkage that snaps to the wiper motor should come with a new retaining clip. You have to fish the linkage assembly through the access holes in the body by un bolting the wiper motor.
remove wiper arm and check splines on wiper motor or splines on wiper arm for damage if damaged replace. Sometimes arms are just installed with a nut and this nut over time becomes loose check tightness.
Place the wipers are in the PARK position, then turn the ignition OFF.
Disconnect the negative battery cable.
Lift up the wiper arm pivot nut cover . . .
It's plastic and just pops up and you slip it off. Next, remove the nut. Once you remove the nut, mark the arm and the shaft or top of the mounting area so you know where to place the arm back on the splines. Then, you use a tool similar to a battery clamp remover and pop the arm off. Installation is in reverse order...just remember to align the splines to the arm.
Is there a little cap covering where it attaches to pivot at base of windshield. If so, pry/flip it up, forward from bottom or end, & you'll probably see a nut to tighten underneath it. Do it when wipers off & in parked position so you can move the arm where you remember it goes, then tighten. Don't reef too ******* it, they aren't that strong and will snap if you go too far with wrench, just real snug. Unless you've stripped spline real good, this should do it.
