Trouble shooting a dead wiper motor

My advice is look up MyMopar and download a number of free service manuals. They all "say something" in section 8 about troubleshooting wiper motors. Make sure you get the right group --that's a 3 speed---the 2 speed/ variable speed are different.
Once again, 273 comes through. You have earned my respect once more. If I can, I might ask you some questions about my '70 Swinger 340. Respect sent.
