2000 100series landcruiser. having a problem figuring out why only the passenger side front and rear locking system won't work. Doesn't work by fob or by manually hitting the button. I had replaced all motors to the actuators about 3 months back so I wouldn't think that the motors would be the issue. I unhooked and checked to see if everything was connected properly as well and everything checked out fine. Is there a fuse that is dedicated to just the passenger side for the locking system? is there anything else that i might be overlooking causing this problem? Please help.
