Hi Rebbecca. Thanks for contacting us today. Most of the time, the symptoms you are describing is caused by an electrical short with one of the wires behind the dashboard. It can be due to a loose fitting ground wire or an electrical relay that is loose or faulty as well. It’s probably best to have a professional mechanic complete an electrical inspection to isolate the source of this problem so the right repairs can be made.
