Hello, recently on my 2007 G35 Sedan with bose system and no navigation, my climate controls stopped working after battery died and was recharged and my car is healthy now, however my climate controls all dont work( cant run diagnosis as the buttons and the radio screen is off) I have checkes fuses and all seem to be fine, any advice is greatly appreciated, thanks.

 

You can remove it and check the wires to see if its supplying power. If its getting power but not turning on then it probably died.
