rear door locks on 2003 Chevrolet Avalanche 1500

is there a separate rear door lock relay that controlls the rear door lock actuators, and where is it located?

Asked by for the 2003 Chevrolet Avalanche 1500
The rear door locks are controlled by separate relays (located in the lower left side of dash fuse box) and the body computer. The body computer sends a ground signal to the lock or unlock relay after the appropriate switch is pressed.
