If the cluster on your 2007 Buick Lucerne CX 3.8 is showing "Drive" while the shifter says "Park" and the car won't start, there could be a few potential issues. Here are some troubleshooting steps you can try:
- Check the shifter cable: The shifter cable connects the shifter to the transmission. If it is disconnected or broken, it can cause the shifter to not function properly. Check the cable and replace it if necessary.
- Check the shift linkage: The shift linkage connects the shifter to the transmission. If it is disconnected or broken, it can cause the shifter to not function properly. Check the linkage and replace it if necessary.
- Check the transmission range sensor: The transmission range sensor is responsible for detecting the position of the shifter and telling the engine control module (ECM) which gear the car is in. If it is malfunctioning, it can cause the car to not start or display incorrect gear information. Check the sensor and replace it if necessary.
- Check the battery: A weak or dead battery can cause the car to not start or display incorrect information. Check the battery and replace it if necessary.
- Contact a mechanic: If none of the above solutions work, it may be necessary to contact a mechanic for further assistance. They may be able to provide additional troubleshooting steps or arrange for a repair of your car if necessary.
Note: Before attempting any maintenance or repair work on your car, be sure to follow all safety precautions and refer to the owner's manual for guidance. Additionally, if you are not experienced with working on cars, it may be best to seek professional help.
