Well, Daox you were absolutely right - it was bad contact between dashboard controller & pcb. After I've re-soldered all 112 pins everything went to normal. Now consumption is ~0.0001Amp.
I've also found an easter egg for my 2009 gauge cluster - part of the screen is covered by the label. Chevy doesn't want competition between aveo and pontiac g3 wave, so they cover the screen to make it looks cheaper.
I've cut a bigger window, looks better now.
Thank you Daox for help.
I didn't add the button. All buttons are on the board from factory. First button is the one we all using, and second is covered by plastic (like lcd screen). I've paralleled buttons with wire. It is not an easy task, because the buttons pads are on the over side of the board and to get there you need to unsolder the screen. Now by pressing first button dashboard thinks that I'm pressing both at the same time and changes the modes. For modes description google for pontiac g3 wave manual. If you want ambient temp on the screen you need to trace wires from green connector pin26 and connect NTC Thermistor.

How much of the screen was covered before?
-
I’m going to guess the upper 2/3 rd’s were covered.
The bottom 1/3 was the Standard odometer/trip1/trip2.
The top 2/3 looks like miles/km till empty or maybe how far siNce fill-up.
Enjoneering can confirm, or anyone else that’s currently ‘tearing apart’ their dash! ��
As Doax said, there could be additional functions on the ‘newer’ top portion, and by ‘ganging’ the function switch you can scroll through to see what others would be available.
Good Find!
Cheers

Sounds like a no-brainer mod to do. A little time consuming perhaps, but worth it IMO.

Need to point out this is a 2009 gauge cluster. I am sure this is not available on my 2006 aveo :-(

You can change modes (check pontiac g3 wave manual for description), if buttons are paralleled.
