Sure hope it's not a Module,Eh? I'm missing something here. AFAIK, it's just a switch, not a module.
Already checked this,..all good.I'm sure you've probably already checked this ... but could your dome light switch on the dome light "console" on the headliner have been accidentally moved so that the dome light doesn't come on when the door is open? Just something to check if you haven't already.
Radio stays on and no "Beep" or "Ding" with keys in ignition or lights on with open Driver door.Not only the dome light, if the radio is left on, will switch off when you open the door, with the key in the ignition, will get that annoying beep, also with the drivers door opened, switch your headlamps manual to on to hear another annoying beep.
Thanks for the info !!! :goodjob:my suggestion if you don't want to go to a dealer then find a shop that can reprogram it there are a lot out there go to acdelco.com and search for service centers in your area
