On my buddies 97 Chevy when his wipers jammed and stopped working, one of the arms on his wiper motor transmission was broken and we ended up replacing it. We removed the wiper arms and the top cowl panel. Then we turned the wipers on and watched the wiper motor and the arms on the wiper motor transmission go back and forth. That's how we found the broken arm. You may want to check yours like that.

Good luck ...............
