My trunk will not open, my gas lid will not open, but gas gauge is not working and i dont know what to do, help!,

What is your question?

I have a 2002 LS 430. My trunk started opening and closing by itself, after doing that for a while now ithe trunck won't open up period! So, after that happens now the gas lid wont open, I can't put gas in my car. The gas gauge is not working, so I dont know how much gas I have in my car. What can I do to get all this back working. It had rained the day before all this happened so we don't know if that had anything to do with it or not. Help!

What makes this problem better or worse?

Nothing we just got up and now the trunk won't open or the gas top and the gas gauge stopped working all in one day..

How long has your 2002 Lexus LS430 had this problem?

I have had this about a week
