My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting 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.
From what you have described here this does sound like a loss of ground or power which will cause all of these issues here.I would start with checking power and ground at the battery as well as to where the cables lead to from the battery to see if any issues are found.If a fault is found with any of the cables or connections this will need resolved to correct this here.
I would also check the fuse panels for any loose or damaged wiring needing repaired.
Thanks Pete
