There are usually 2 on those, a main BCM and an auxiliary. The main unit is tucked behind the knee bolster trim under the left side of the dash, the other one is in the center of the dash behind the air bag assembly. What is the issue you are having?

Drivers door lock/unlock. Key in ignition reminder. Headlights on reminder. No dome light when opening drivers door. Also maybe unrelated but no windows or mirror controls on drivers door master
