I always suspect the dimmer, but, after looking at the wiring info, again. The low beam is grounded through the head lamp switch, the high beam is grounded through the dimmer. I'd replace the switch not the dimmer. Thanks for the donation, it all helps. I can send a wiring diagram if you want?
I need to add, there is one more check. There should be multiwire connector under dash close to steering column, lite green wire coming from the steering column should be ground for low beam. If you ground that wire, low beams should work if the problem is the headlamp switch/wiring circuit. The wiring info is causing me a problem because the low beam circuit also comes through the dimmer. I hate to see you spend money on the wrong part?
