Pontiac Grand Am non-functional gauges and gear shift stuck in park, possible wiring issue on Pontiac Grand Am

Some Pontiac Grand Am owners report experiencing non-functional gauges, which may be linked to issues with the ignition switch, erratic readings, or complete gauge failures potentially caused by a failing instrument cluster, wiring problems, or faulty sending units. Additionally, some owners have encountered gear shifts stuck in park, often due to a faulty door ajar switch or wiring issues related to the body control module (BCM), which may mistakenly indicate that a door is open. To address these concerns, it is advisable for owners to check the ignition switch, inspect the instrument cluster and wiring connections, and investigate the door ajar switch and BCM. If these troubleshooting steps do not resolve the issues, seeking professional assistance or consulting Pontiac Grand Am owner forums for further advice may be beneficial.
