… door locks gone crazy

[Shubbydog]

I think there is a relay that sends 12v to your lock relays. Worth a check.

Have you checked your relays for the power locks? After all the steps you took already and no luck…. Sounds like a suspect relay or bcm freak out.

Appreciate the input. Definitely crossed my mind that BCM has fried/glitched out somehow. But hopefully not *crossing fingers* .. but in regards to the relays.. Happen to know location & relay#(s)?

My truck didn’t come with an owners manual so i am stuck resorting to google. Google search pulled up this info:





Which is weird as hell.. because i scanned every block and there is only a vague entry for “left doors” .. but there is no entry anywhere for “right doors”.. actually there is no other entry anywhere for ANY other doors.. so the left doors are controlled by fuses/relays but the right doors are not.. lol wtf .. that does not seem right.

Plus #43 under the dash looks like a small fuse from the diagram, def not a relay. There’s a crap ton of relays on the engine fuse block that are either unused or don’t have info available on what they are

It’s possible I’m overlooking. Getting late and tired right now.. but when i looked on another website pretty much the same info came up.

you might want to check the x1 connector passenger side and see if there is corrosion or maybe bad connection in there.
all the pins to door locks on are that connector

So i checked that harness and it’s impeccable. I wanted to test each relevant pin with the multimeter but apparently i don’t have a setting low enough to get a proper measurement, or i just don’t know wtf I’m doing (or both) electronics is not my strong point

But to the feel test the pins are secure and tight and so clean looks like it just rolled off the assembly line.. wouldn’t you all agree ??










I also looked at fuse#43 on the driver’s side.. looked OK to me


I am starting to think BCM, or pinched wire somewhere in any of the harnesses..

Orrrr…. What? Other than the current possibilities of:

-Pinched/corroded wire hidden somewhere either in wiring harnesses or battery cables
-BCM issue

What else could it be?
