Windshield wipers won't move

It has been snowing here all day, so I lifted my blades off the windshield this morning. When I came out this afternoon, I put them down and turned on my car. I had apparently forgot to turn off my wipers this morning. So as soon as the car started, they tried to move, and I heard a slight popping noise. Now they won’t move. I can hear the motor working, but the wipers don’t budge. What should I do, can I fix it on my own? Any help ASAP would be great! Thanks

Reported for forum change.

Moving this thread to In My Humble Opinion.

There’s a nut at the end of the wiper where the motor shaft connects. See if tightening it helps.

Thank you!
