    I just bought a 2016 5700xe and the power door locks aren't working on it. I checked the fuse and it's fine. Any idea where I should look next? I didn't see a relay listed for them.
    I do have keyless entry on it also, although it's not working either.
    Thanks

    Your truck is spec'd with the keyless entry module. There is a 15 amp circuit breaker that controls this. upload_2020-10-1_8-45-58.png


    PDM#1 has the B10 circuit which is F5.

    Here is the location of the PDM#1 (this is the dash mirrored ((looking at it the other way)))

    The keyless entry Module is located on the backside of PDM#1...ish.

    So...there could be multiple things.
    1. The UNLOCK and LOCK signal could not be getting to the module (which is a pass through i think).
    2. The module could not be getting power and/or ground
    3. The switch could be faulty.

    If you are still unsure and unable to fix...you might need to take your truck to a certified WST dealer.
     
    CousinVinny Thanks this.

    Thanks for those diagrams. I'll break out my multimeter and see what is going on.
    Thanks!

    I have a 2019 5700xe and had the same problem, WS replaced Door lock actuator.
    Also had to have the window regulators replaced
