What is causing courtsey light not to come on when door opened

Not with any door, No to dome light coming on overhead. Reading lights work.

check the dome light switch,make sure someone has not turned it to the OFF position instead of the DOOR position.

Not seeing a dome light switch, where would it be

on the dome light.most vehicles have a 3 position switch.on,off,door.yours may be automatic being an 09,but still should have a push button or slide switch.i just noticed your user name,i'm 20 miles west of Charlotte.

Replaced dome light bulb and presto. Was born and raised around Wilson. Now in Virginia Beach but love my Tarheel BBall. Thank you for taking the time to help me. Hope you and your family have a blessed Xmas
