Odd problem where the buzzer is always on if headlights on

[bennylava]

Hi all. I have the door chime on my truck, where a loud chime plays when you accidentally leave the headlights on. Got that one installed in the factory spot instead of that horrible screeching sound the older chevys came with. Anyway the loud chime stays on the whole time the headlights are on.

This started happening 3 days ago, and I'm hoping someone here might know what could cause this. No matter what you do, if the headlights are on, it's blaring the chime at you. Any help would be greatly appreciated, thank you.

EDIT: It's an 87 model if that matters
