Fixed the mirror and returned the new motor
Fixed the mirror motor today. As it turns out, the body mechanics did not fully at the black driver mirror connection from the mirror controlled, and while it made good enough connection for the up and down function to work, the left and right did not. Well, after playing around for an hour and firmly reseating the connector, it now works. Lucky me, as the new motor wires did not match the colors of the old one, and figuring which ones controlled what by trial and error would not have been fun. Alls well that ends well.
