I just picked up a 00 Sonata and am having a wierd problem after installing a radio and HD tuner. I put everything back together and everything looked perfectly normal. I went for a drive to the store and again everything seemed normal. I then get in the car a little while ago after it got dark and realize I have no backlight for my speedo cluster and no back light for my heating controls. The wierd thing is that I have the orange and green lights like the gear indication on the speedo cluster and the AC, defrost indictators on the heating control part. What the hell could I have done to make just the backlight go out on these two things? I checked my fuses and none of them appeared to be blown. I have installed about 15 different radios in my 99 Sonata with no problems at all and for some reason on my first install on my 00 I have this issue. So anyone have any ideas?
