In my case, I replaced the actuators and switches then discovered the real problem - the door lock rod mechanism was rusty and hanging up when the actuator tried to move the lock. I applied WD40 and all was good. They still hang up once every few months, but they work fine most of the time. I will have to remember to lube those rods the next time I have the door panels off. Even in the desert you can get rust in enclosed spaces like door panels. I suggest you remove the door panel and operate the lock switch to see what is going on inside the door - a flashlight and inspection mirror will help.
