My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
I dont see how the alarm would have caused issues with the dome lights here.This sounds to be more of an electrical fault causing all of these issues with a loss or power or ground possibly.
What needs to be done here is to have the fault codes read out/checked using a fully compatible scan tool that will plug in and can communicate with all computers to see what codes are set.Once this is done any codes set in any of the computers will help to diagnose and locate this fault here.
This may be a component like a body computer at fault here needing replaced to resolve this issue.But this may also be an issue with a component like a relay that has failed so having the codes checked/read out will help to diagnose and pinpoint the issue here.
