Think I found the problem. Relays would click when turning on wipers. Cleaned out switch was functioning perfectly. High and low would work, so I didn't suspect the GEM. Tore into the wiper motor cover to attempt to bend the electrical prongs back in case they were not making good contact. Shockingly, I didn't see any metal conductive disc on the cog wheel or any prongs on the cover to touch it...almost like the thing had exploded inside. Oh well. Guess I'm replacing the wiper motor...it would have been nice to not have to take off the wiper arm and stuff...oh well...
