WE have HHR 2006, the battery went dead and now the radio does not work at all. We have checked the fuse in the fuse box and it is ok. I understand there is one in the back of the radio, how do we get to that fuse
Don't even waste your time. GM has their cars designed to make them lots of money after the sale. Their biggest "got'cha" is from disconnecting the battery or letting it run dead. If the engine starts and runs properly, drive it to the dealer to have the radio reprogrammed.
