Headlights(low beam), and wipers not working

Asked by Charles Apr 20, 2019 at 04:12 PM about the 2004 Pontiac Montana

Question type: Maintenance & Repair

I have a 2004 Pontiac Montana and i just changed
the dimmer switch due to my low beams not
working. High beams work and while researching, I
read that it could be a dimmer switch. I replaced
and still same scenario? Any suggestions?

1 Answer


If my wiring diagram is correct, see the tan wire from dimmer switch, that is voltage for low beam. Use a test light, headlamps on lo beam, the tan wire should be hot, is it? Maybe problem with wiring connector or wiring circuit from dimmer to lo beam.
