2004 Mercury Mountaineer

For the last couple of months when turning off the vehicle I had to turn off the interior lights button which also turned off dash lighting. If I did not do this the interior lights would remain on. An no it was not clicked all the way up. Also, occasionally the door open signal would illuminate and after a check of all doors found that turn on the interior light switch and then off would cancel that alert. Today my car would not start. There is a mild “want” to start. But after attempt to start the instrument panel flutters for a few seconds. Is this a computer issue?
