Just took delivery of my beautiful 1971 Mustang convertible all original car. Delivered to UK from new. Been under wraps for most of the last two decades runs and drives perfect . I have a problem with the front Right indicator though . It works on the hazards and the side light but not when I indicate. The light comes on the panel and the rear but nothing on the front. I’ve replaced the bulb but to no avail ,Any help greatly appreciated , regards Chris
