2004 Toyota Corolla Power door locks

Hi, i just bought a 2004 corolla. and the issue is 2 of the 4 doors wont lock or unlock when i hit the lock/unlock switch. same thing happens if i hit the switch on the passenger door. now the doors that are not responding are the door behind the drive and the passenger door. just on more thing I can manually lock and unlock the doors meaning by hand. any ideas?
