Tonight I discovered it IS a pull-back switch. I just wasn't pulling back far enough to "click" the high beams on! This stalk travels farther than other cars I've had (even GM'*) and it takes a far amount of backward pressure to switch the lights over. The click is kinda quiet and doesn't always sound, but the high beams work fine after all.
So, at the end of the day the problem was the loose nut behind the steering wheel. (just kidding of course) I'm glad you figured it out.
