Still working on this. Here's my update; after driving around this morning. I got HEAT! Unlike before. My engine temp is actually registering between 80 and 90, before it barely made it to 80. The blower did not work until after the engine was warmed up and then turn off and back on again. I'll test the Regulator and Blower Voltages tonight after getting home.

Otherwise, it's still a "I hope the fan works today" situation.
