Instrument Panel and Radio Lighting - Electrical on 1999 Chevrolet Tahoe

WHen I first bought my '99 Tahoe used, the radio illumiator lights were half out, so the dealership split the cost of a replacement radio with me(a rip off in itself). Now, it looks light abuilb went out in the instrument panel because only half of my odometer lights up, then half of my radio illumator lights went out, the gas guage starting vibrating and flip flops upon starting he car and then passenger window wouldn't work until I slammed the door. Could this all be related? On the illumiating light problem would it be an electrical problem instead of a bulb problem? I don't want to have to fork out on another radio after only two years.

I am afraid you are probably going to need to have the radio and now the instrument cluster also repaired or replaced in your 1999 Chevrolet Tahoe. The back lighting bulbs are no longer replaceable by do-it-yourselfers, or most repair shops for that matter - most all manufactures are the same in this regard.There are special auto electric repair shop which specialize in radio and cluster repairs. In most cases the failed component must be removed form the vehicle and taken in for repair. The fuel gauge can probably be repaired at the same time. The problem with your passenger door window is most likely the window motor itself inside the door. I don't think there is a larger electrical issue causing these failures.
