help door locks dont work

[PWINCE$$]

I need to know the cause of this problem whenever i lock/unlock my doors the passenger door and driver side rear door doesn't work. I have a keyless entry with my alarm and it doesn't lock or unlock with it too? Maybe i need a new actuator for each door? It's also weird because when I go to work early in the morning when it's cold out, all the locks work sometimes?

Yeah man, I had the same problem a few months ago, changed the actuators and now it works perfect.
