My problem is as follows: drive's side power door/window lock switch does not lock/unlock passenger door. However, passenger switch opens both doors and driver switch opens rigth door and both windows. The only problem is lock/unlock passenger door from driver's switch. Please help. I'm not good at this things, but am willing to try.

 

exactly the same problem here,
Lock switch is good, actuator is good, just dont work

 

My power door locks aren't working properly. They intermittently work using either key fob or either front door lock switches. I replaced the key fobs and still no better. Any ideas?
