I always start with simple. Fuses first , then see if the system (in this case the switches) is doing what it's supposed to. Then I move you the more detailed checks.

Can someone confirm for me what the exact location of the power lock doors fuse is on my truck? I tested switches and they are good. It's either actuators or something else.

Thank you so much. Ok fuse is good and switches are good. Must be actuators or wiring somewhere. Odd thing is both driver and passenger door locks won't work. What do you think I should check next or do?

 

If you have power leaving switch, you have answer

 

I was going to say (as I mentioned previously) to check power at the actuator. You've verified power going into the "system," now check if you have anything coming out at what's supposed to be working. If you have power there , then, as mbb stated, "you have your answer."

Yep.
But chances are really remote anything is wrong with wires in the 24" harness between switch and actuator.

If go thru the trouble to remove door panel and unplug actuator to test there, might as well have another on hand to replace it imo. You can always return unopened parts if they are bagged.

 

True, and true.

 

Awesome. I ordered both actuators for it. Do you think that the rear doors would have any issues too or just replace front two and go from there?

 

Most people I know with this generation vehicle f150 and f250 have had at least one go bad.

I dont know anyone thats had all.

i wouldnt worry about good ones unless stop working. I had one go bad several yrs ago . Only one.
