I picked up my car today from having my transmission rebuilt and the digital clock no longer worked. It worked when I took it in but did not when I picked it up. The radio works but the clock portion has no numbers showing and when you tap "min" or "hr" nothing happens. Any thoughts? I drove it directly back to the mechanic when I noticed and left it with him but he is stating that he does not know why it would happen. Could it be something not connected or something in the reprogramming of their work.
