Chevrolet Vectra 2003 145000 miles
Hello, the problem with my vehicle is that, when stopped at traffic light, it purrs continuously. I need to set a gear so that the annoying noise disappears. But since yesterday, gears cannot be changed, or at least they are not registered. I was told it must be the computer that is failing, but I do not know how to make sure that this is the problem and where to buy one. Even more, the interior light has stopped working.
