Re: Windshield wipers will not move. Arms from motor
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.

If wipers arms are not moving and motor operates, look at base of wiper arms. There will be a cover concealing a nut on each arm. Check and make sure the nuts are tight. If tight, suspect wiper transmission disconnected from wiper motor assembly and cowling will need disassembly for inspection/repair
sounds like a loose nut. there are nuts that hold the wiper arms on, they may be under a cover but theyre at the base of the wiper arm. also there's a nut that holds the wiper linkage onto the wiper motor. if you can move the wipers independently, it's the nuts connecting the wiper arms.if you move one arm and the other moves with it, it's the nut holding the linkage to the motor.
Does the wiper motor run? If you can hear the wiper motor run, the wipers arms may have disconnected from the wiper motor,you will have to remove the wiper arms,and the plastic cover to access the wiper motor,and check for damaged parts.If your wiper motor does nothing at all, you probably blew a fuse do to the resistance on the arms,refer to your owners guide for fuse panel, and fuse locations. hope this helps
Pivot Shafts and Linkage
The windshield wiper assembly is mounted below cowl top extension (021A36) . Linkages are connected with non-removable plastic ball joints. Windshield wiper mounting arm and pivot shafts are an integral part of the windshield wiper and are serviced as one unit.
Disconnect the battery ground cable (14301). Refer to Section 14-01 .
Remove antenna mast from the antenna base.
Remove cap on LH and RH windshield wiper pivot arms to expose nuts retaining the arms to pivot shafts.
Remove two nuts, one from each of windshield wiper pivot arms . Lift wiper arms to service position, carefully rocking them back and forth to loosen them from the pivot shaft. Lift off windshield wiper pivot arms .
Remove seven screws retaining the cowl top vent panel.
Disconnect windshield washer hose (17A605) at LH side of vehicle just ahead of where it enters cowl top.

They might well be!
Check under the hood / bonnet at the linkage connections.
Occasionally, the bolt / fixing can work free, allowing the motor to work as normal.
This does not transfer the motion to the wiper arms and you get the motor noise but no movement.
Depending on the car, it could be easy - or very difficult to access the linkages.
Under the cowl (it is a plastic piece that the windshield wipers come out of) are the wiper arms that connect to the wiper motor. There are plastic parts that hold the wiper arms to the wiper motor. Lots of time these plastic parts dry out and break and the wiper arm will fall off the wiper motor. I would bet if you tried to move one of the wipers by hand both of them would move with little resistance. This would tell me that the wiper arms are disconnected from the wiper motor. The parts to fix this are easy to get. I know the motormite HELP line of parts used to have the plastic bushings to fix this problem.
