Your problem is this:

Both your front and rear limit switches are "On" So basically this means that your front limit switch is bad (the one near the windshield.) Please remove trim above window, and remove limit switch. Press switch with your fingers a few times should hear a "click sound" or use a Voltmeter and test for continuity between leads on switch. Replace or repair switch as necessary.

**Edit**
Might want to remove power cable comming off battery before trying this. As soon as you remove the front limit switch the seatbelt will try and move and wont stop until the switch is replaced. dont want to burn out your motor******
