The switch assembly on this year and model is an actual control unit/ecu as well.It has to be programmed by a GM dealer after it is installed using their computer before your vehicle will recognize it for proper operation from there.If this was not programmed this needs done.A dealer will charge anywhere from a half hour to an hours charge for this.

This is due to the switch not being programmed and recognizing the latch signals properly to operate the dome light properly.I have seen this occur before as well.This switch assembly you installed is called a drivers door module and it does need programmed to work in your model properly.
Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.
The other common fault is broken wiring where the wiring leads from the body to the door or inside the door needing repaired.I would have the wiring checked then to see if any broken wiring is found at fault needing repaired or replaced.
