Hy.i'm from romania.
I have a problem with the clock.
The clock permanently reset itself, when i drive or when i start the engine.i ceck teh fuses, and the batery cable.they are ok.
You have this problem with your chevy?
I had this same problem when receive my Aveo LS 2008 and the clock was replaced for a new one in the agency. In case that yours is not on warranty, you can review the same clock and put a plastic between the clock boards. There is two boards that probably have contact and cause the problem.
I have news.I was ti the service again.
They made some soldering on the motherboard clock.
After that they tell me as everithing is fine, and the clock will be working.
Well... the clock,still reset it self.I go to the service again and they discover a diode on board clock that went randomly.They change tehe diode and everithing is ok right now.
