Directionals aways lite

[jobrla]

I feel stupid asking this question because I have had several times on different chevy's but can't remember what the fix was.

When I turn on the head lamps, the directional indicators in the instrument panel light up also. If I turn the head lamps off and turn the side markers on, they blink, they also blink when the head lamps are on and stay on when turn indicators are turned off.

Checked all grounds, all good.

Any info, I appreciate

thanks
Jody
