If a 1993 Dodge Spirit won't go into park, the issue could be related to a malfunctioning transmission linkage, which connects the gear shift to the transmission. It might also be due to a worn or damaged shift cable, or a problem with the transmission itself. Additionally, a faulty brake light switch, which is necessary for engaging park, could be the culprit. It's best to have a mechanic diagnose the issue to determine the exact cause.
