Thank you very much for this detailed tutorial. My original problem was a bad bulb. When I removed the blower knob to replace the bulb and reattached it, the blower quit working. I figured I was in the hole for a new switch and an evening of labor. After taking the dash apart and looking at your photos, I discovered that the wiper arm (the thing you glued on) somehow got above the copper bar. I had to very carefully bend the wiper in the off position until it slipped back under the bar, and I was back in business.
