Headlights flash with turn signals
72 Blazer - with the headlight switch turned off, they flash along with all of my dash lights when my turn signals are turned on. I feel like it's a ground issue, but what grounds should I start with? Dash ground, where is that located? Headlight grounds Turn signal grounds maybe? I hate electrical issues.

Re: Headlights flash with turn signals
Both directions do it and the tail lights dont flash like the headlights.

Re: Headlights flash with turn signals
When ever I track down a problem like this, it does seem to be ground problems. Check the grounds at the headlight bulbs and the turn signal bulbs. also double check the bulbs. Once had a bulb filament break and short to the other filament causing all sorts of strange issues. this was at the rear bulb
