Assuming the other seat adjustments work, and the switch tests okay, remove the seat, turn it over and inspect the forward/backward mechanism. You will probably find something broken.

If your 2003 Town and Country's power seat moves forward but not backward, it could be due to a faulty switch, a jammed mechanism, or an issue with the seat motor. First, check the switch for any signs of damage or wear. If the switch seems fine, inspect the seat tracks for any obstructions or debris. If the problem persists, it may be necessary to test the motor or wiring for faults.
The seat moves forward typically through a mechanical or electronic adjustment mechanism. In manual systems, a lever or handle is pulled to release locking pins, allowing the seat to slide along tracks. In power-adjustable seats, pressing a button activates a motor that moves the seat forward. This movement is designed to provide users with customizable comfort and support.
It'd probably be easier to move the tracks forward completely. Or mount the seat with a forward offset.
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.
To move the seat forward in a vehicle, locate the seat adjustment lever or button, usually found on the side of the seat. If it’s a lever, pull it up while pushing the seat forward; if it’s a button, press it in the direction you want the seat to move. Adjust until you find a comfortable position, then release the lever or button to lock the seat in place. Always ensure the seat is securely positioned before driving.
Sounds like the motor or gears have a problem. You can try to find the wiring and power the motor up in reverse manually. I had a problem with a seat in a Volvo and it allowed me to maually turn the gears to move the seat back itno a position where it was comfortable for the customer to drive. I then disconected the power to the seat motors so they couldn't move it by accident. I had to get inside the seat to do this.
At the back of the seat, move the seat all the way forward to access them...
