Combination Brake/transmission Problem
Have an 2007 Cobalt 2.2 that is stuck in park. This has happened previously, and the culprit was a blown fuse in the passenger footwell fuse block. I don't remember exactly which fuse was blown last time, but this time the one blown was #9, a 10A fuse for the brake lamp circuit. Any attempt to insert a new one just results in it blowing the moment the contacts touch the terminal. At this point, I have replaced both brake light bulbs AND the switch at the top of the brake pedal, and inspected the wiring to the extent that it can be readily seen, all with no effect on the short (wherever it is).
This issue occurred spontaneously without any other related (or even suspicious) issues leading up to it. The car was running fine the previous night.
