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.

Usually the fault with the alarm going off can be due to an issue with one of the door latches (usually the drivers front as it is the door used the most) that is sending an incorrect signal on what position the door is in.This can set off the alarm like this here.I would have the door latch signals checked for any issues.This usually requires a fully compatible scan tool to check fault codes in all computers as well as check the door signals to locate a faulty latch needing replaced.

As for the tail light not working check the wiring at the tail lights for any loose connections or corroded or damaged wiring.If this is or was checked and found to be o.k. let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
