All the door locks do not work from the switch

These could be a couple of things, but we need to start with testing the door switch and see if there is voltage coming from the switch to find out if the switch is the issue.

Clearly the door locks work so we need to start with this info and see what we have.

Here are a couple of guides that will help with this:

I am attaching the wiring diagram below but if the issue is that none of the switches work then more than likely the issue is in the body control module. So, we simply need to check the voltage coming out of the BCM for the door lock circuit and find out if it is sending the signal. If not, we need to replace it.

Let me know what you find with this, and we can go from there.
