I bought a Hummer 2 limo 2009. The AC stopped working and they traced that it's this thing 






that got burnt. We checked our local spare parts dealers and they don't know what it is, there is no writeup on the device. I bought the vehicle since February and this is November, I haven't fix this, please help.

That's clearly not a "standard" item and based on its appearance, it appears to be a one-off or low-volume custom made device.
Tracing the wires to wherever they go may provide some additional clues to its purpose.
Also, you might see if you can track down the "coach builder" who turned the Hummer into a limo. It seems likely to me that it's something they added and they might be able to provide some information or assistance.

After contacting a limousine manufacturer I Finally found out that it's Fibre Optic Light Engine used in the hummer. I think the people that worked the car before, connected the AC control to the Fibre Engine, that's why after it got burnt the AC control is not working. Though the one used is an old model and can't find it anywhere. Thanks everyone for your input.
