13 tahoe ltz. I have a tech 2 and would like some insight into this. Drivers door light don't light up,rap stays on but key in and door open chimes. Ran tech 2 and it says door is open at the ddm like it should be.checked bcm and it says rap is off but radio is still on till it times out and no overhead light. Checked the wiring the best I could. Is it the bcm? It's almost like it's a stuck relay.
