I have a 99 s10 Blazer with about 190k miles. I got in it a couple days ago and I have no odometer, the fuel gauge is dead, and no bright dim indicator. The headlights work, both bright and dim, just no little blue light on the dash. It is manual trans. The main odo comes on when I turn the truck off, but don't push the key release button and turn the ignition all the way back to remove the key. Key off and key in the run or start position, no odometer. The key reminder dinger/bell is working like its supposed to.

I've checked the fuses. Where do I go from here? Ground issue somewhere? Relays? Key switch? I don't even know where to begin testing.

I have a digital multi meter, test light, and a elm-327 type Bluetooth code reader with the Torque app on my phone.
