Yes, you can manually release and open the trunk on a 1999 Mitsubishi Diamante. If the trunk release button or remote is not functioning, you can access the trunk release lever located inside the car, typically near the driver's seat. Additionally, if necessary, you can fold down the rear seats to reach the trunk from the cabin. Always refer to your owner's manual for specific instructions related to your vehicle.
To change a tail light in a Mitsubishi Diamante, first, open the trunk and locate the tail light assembly. Remove the screws or clips securing the assembly, then carefully pull it out. Disconnect the electrical connector and replace the burnt-out bulb by twisting it counterclockwise. Finally, reassemble the light assembly, reconnect the electrical plug, and test the new bulb before closing the trunk.
