When you ask any tech question, we need to know: YEAR; MODEL; MILES; any recent work done just prior to symptoms complained of began. When you ask a vehicle questions, it goes in the vehicle specific section..... ie ALL H3 questions go in the H3 Section. We got no idea what vehicle you are talking about. If you would like to add the suggested info, I can move this Thread for you.
