3 of my 4 doors do not u lock with the key fob or the door button. Trying to rule out a fuse or relay issue 1st before checking other things. But I can’t find where Rhodes fuses or relays are located.

Hi,

The locks receive power from the body control module. The first pic shows the fuse that powers the BCM. However, I feel there would be several other things not working if the fuse is bad.

The second pic shows wiring to the BCM. I highlighted 3 wires. Those wires power all of the power door locks.

If you look at pic 3, it shows the three wires from pic two and where they connect to the switched. The total schematic is 3 pages long, so I tried to break out only the important things.

If I was to check this, I would first confirm there is no power to the lock actuators in each door because if there is, then either the switches or actuators would be bad. If there isn't power, work back to the switch to see if there is power to it. If there is no power, then you need to check back at the BCM. However, since one works, that tells me power is coming from the BCM.

Let me know if any of what I explained makes sense. LOL If you have questions, let me know that as well.

Take care,
Joe
