I'm trying to help my grandmother out with her van. She has a 2013 Dodge Grand Caravan and said her high beams were not working. When you push the blinker switch forward, it stays on low beam. It will flash the brights if you pull it towards you, so I know the bulbs are working. I was thinking either the relay or the combination switch. I can't find a relay that is labeled for the headlights. Anyone have any ideas on what to test or know which relay it would be? Thanks for any help.
