The wiper slowed and finally stopped working altogether. There is a bit of movement when starting up the wipers.

wiper motor could be the problem as contacts are track type so can partly operate until turns to a dodgy track

hi there . think they may need a bit of wd40. spraying on the shaft.
probably just road dust and debris. making it stick.

the cause for the wipers not parking is the park tab on the wiper motor bracket is bent, replace the wiper motor bracket. as for the wipers not working at all, could be a faulty part. fit your old motor back onto the new bracket and test.

unplug the wire at the wiper motor and then turn the key on and then turn the wiper switch on and test the wires at the plug with a 12 volt tester . if u dont have any thing then ur wiper switch is bad , if u have juice at the plug then it sounds like its the motor.

The park position is controlled inside the motor/actuator assembly. Not sure if it can be repaired. See if it is assembled with screws versus rivets. A new assembly is less than $100.

If they slowly died it is most likely the wiper motor. Over time the brushes in the motor will wear down and the motor will need replacement.

Common for the linkages to fall apart or jam. You need to remove all the plastic cowling and have a look, it should be obvious when you see it.

there is one wiper motor,in the off position,reset yuor wiper arms and tighten the nuts that hold them down on the mounting points of your wipers

I had the same problem. I thought it was an issue with a blown fuse, but also noticed that the rear wiper was very stiff.
I solved it by opening the rear window (so the wiper is not clicked into the motor) then squirt some WD40 into the wiper mechanism (I put the oil in from the outside). Gently move the wiper from side to side until it starts to free up - after a couple of movements the wiper should be moving freely again. No issues since.

At the same time, check that the washer jet is correctly angled. Mine was squirting directly into the wiper which may have caused it to rust up a bit.

well the good thing is you know the wipers work !! , I would start by seeing if the washer squirters work when using the Wiper lever . and I would also see if it worked on fast speed and slow speeds . If it does you may have a wiper switch that has gone bad ! ,
