What would it entail for me(myself) to replace my driver's door jamb switch?

What is your question?

I currently have none of the following which I think is due to the driver's door switch not working, but I'm just guessing. No seat belt buzzer, no buzzer for key left in ignition, no dome light when driver's door is open, no chimes when headlights are left on. If a mechanic or the dealership needs to fix this problem, I was unable to find anything in your "Estimator" screens related to a door switch. I would appreciate your help. Thanks.
