Yes there is a backseat, however, if someone is over 5'5" they will be very uncomfortable.
To remove the seats in a 1994 Mitsubishi 3000 GT, first, slide the seat all the way forward to access the rear bolts. Use a socket wrench to remove the bolts securing the seat to the floor. After removing the rear bolts, slide the seat back to access and remove the front bolts. Finally, disconnect any electrical connectors for power seats or seatbelt sensors, then carefully lift the seat out of the vehicle.

The power seat on your Mitsubishi Diamante may not move back and forth due to a blown fuse, a malfunctioning power seat switch, or a problem with the seat motor itself. Additionally, there could be an obstruction in the seat tracks or a wiring issue that prevents the seat from functioning properly. It's advisable to check the fuse first and then inspect the switch and motor for faults. If the issue persists, consulting a technician may be necessary.
As odd as this sounds check under the back seat. My brother has a new model Lesabre and he had to take the seat part of the back seat out to change his battery.
