First off, I currently have the ignition switch issue which causes the blower to only function on Level 5. Resistor and blower were replaced, which fixed all my other issues with it except for 1-4 not working/turning my headlights off. I plan on buying the switch at some point.

Now, that said - my lights have become increasingly dim (slowly, but surely), dimmer over the last year - when the ignition switch issue started as well. This means all of my lights. Dome lights, door panel lights, dash lights (to some extent), and of course headlights/taillights.

So my question is, can the ignition switch issue be causing this as well, or is it more likely that the alternator is going out? I can live without the 1-4 setting so the ignition switch isn't a priority item at the moment, but if it's causing these additional issues then I'd likely replace it sooner.
