- Disconnect the negative (-) battery terminal.
- Remove the lens and open the sunglass case cover from the overhead console then remove the 2 screws holding the overhead console. And disconnect the connector then remove the overhead console lamp assembly from the headliner.
- Remove the trip computer (A) mounting screws (3 EA), and then disconnect from the overhead console.
- Installation is the reverse of removal.
