2000 GP door lock solenoid replacement

The door lock on my sons 2000 GP GT will lock but not unlock on the passenger side. It makes noise when you activiate it but the small lever on the side doesn't pull back up. Does anyone know where I can find instructions on replacing this or can someone on here tell me. Any help appreciated.

My 03 Gt has this problem as well. Let me know if a new actuator(solenoid?) fixes it.

The new solenoid fixed the problem. I sent it to the shop to get it fixed because I didn't have the time to mess with it. Maybe someday the procedure on how to change it will be on here.
