I have a 2000 gs4 and my Dimmer Switch is acting funny? I went to work today and my Speedo came on but very very dim where you can barely see the gauges. Later in the afternoon i went to check it out and now it works but now my dimmer switch doesn't do anything. It either lets me turn the gauges on or completly off. It doesn't have a in between. It only turns off when the dimmer switch is all the way off or if I turn the switch a little bit it will be on. All the other lights that usually dims works fine. I don't know what I should do. I checked all the fuses and all of them are good. I think it might be the dimmer switch but not sure. Can anyone help me out. Thanks in advance for any help.

Try it when it is dark out.
