I have a 2001 Jeep Wrangler Sport 4cyl.
When I have my headlights on the left turn signal does not flash, with the headlights off the left turn signal flashes but so does the odometer . Right side works fine. I replaced the left multi-function switch this did not fix it. Checked the ground at the tail light, cleaned up bolt threads and body threads still not fixed. Can any one help here??
