Well, we do try to help
My guess is that the wiper pivot shafts are well and truly corroded, preventing any of the works from rotating.
Unplug the multi pin plug at the wiper motor.
For starters, check the fuse for the wiper motor, should be a 10A, 2nd down from top LHS of engine bay fuse box.
If you know how to use a multimeter, check that power is on this fuse when the ignition switch is on .
That power should then be at the plug for the wiper motor on the Blue wire with Red tracer.
Check that the pins and connections in the plug and socket are in good condition, clean with some spray contact cleaner if you have some.
I now suggest you disconnect the wiper arm linkage at the rear of the wiper motor so that the motor has no load.
Plug in the wiper plugs and operate the wiper switch to HI and LO speeds and see what happens with the motor.
The switch actually provides the earth required for the motor to operate.
If the motor operates normally, then all is well up to that point.
If not then more electrical checking is required to find out what is wrong.
At this point, check to see if you can move the wiper assy. by hand.
DO NOT FORCE IT, just see if when the wiper arms are off the glass, you can make them flip flop by rotating the motor crank.
If they move, fine.
If they don't, the whole shooting match should be de-mounted from the car and re-furbished.
Try all this first and see how you go
