windshield wipers out of sync

2000 grand prix.. first they weren't working and now one moves and the other partially moves.. out of sync.. what could be the problem?

one seems stuck at bottom like it wants to move.. I did tighten the screws

These come in on each other right? Not sure when the changed that as I had a 1996.. What I found is the main spine holding the wiper gets stripped... Sometimes the wiper end itself... Have you removed it to inspect?

You have one motor that drives a linkage. You should be able to tell if the arms or axles are stripped by pulling both off and comparing the good to the bad.

You may have to remove the cowl piece to check the linkage.

I'm thinking one of the wiper arms loose or stripped.
