SL2 Wiper pivot arms

The pivot arms of the wiper seems seize on my car. Is this a commun problem
on this car? Is it possible to fix it just by cleaning the linkage and the
pivots or I will need a replacement?

Thanks!

 

Easy to fix.
Mine have broken twice.
Lift the lid and remove the plastic at the bottom of the windshield with a
torex.

 

Same thing happen to my 92 SC2, I went to the junk yard bought a new set of
arms and motor for $100 Cdn.
