Took mine out and peeled the leather off. tested all connections with Ohm meter and they all read good. put the damn thing back together and reinstalled to check for the relay noise. clicks like it should. seat works fine. must have had a bad harness connection somewhere I'm guessing... Moral of the story? CHECK FOR LOOSE HARNESSES FIRST! I swear I have fixed more GM gremlins by unplugging and replugging the harnesses over the years. hope this saves someone the trouble someday.
