Hello and welcome to just answer, my name is ***** ***** master tech here to help. I cannot see or hear your vehicle so I depend on your input to my questions so I can help you better. I read your question and notes what you have tried so far. I have a question before we start, have you put a code reader on it to see if there is any codes? It might be a wise move to put a scanner on it to read all the perimeters.
