Recently I noticed that when I turn the headlights on in my 74 Javelin the left blinker light illuminates. It has been intermittent. I'm thinking I've a ground in the column but I have no idea how to find it. Any suggestions?
Checked the bulbs and they were good. Checked the ground in the trunk and it was good. Noticed some corrosion on the front blinker housing prongs. Used a bit of emery cloth and cleaned them up. Magically everything works correctly now.
