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

Sounds like a grounding issue. A bad ground will always make the functions act goofy. In this case, says the lights are on when they are not.
Next, it could just be a bad buzzer. Try swapping it out with a known good part. If the known good part still buzzes, then that would rule out a bad part and it’s most likely a bad ground.

This will happen when the instrument cluster is not plugged in. Check your cluster plug to make sure it is making contact with the printed circuit. It is a tough reach but you might want to see if you can reach behind the cluster and wiggle the plug.

Thanks! I've been having trouble with all the gauges lately, except the speedo which is cable driven. Sounds like you're onto something here.

I went and bought this buzzer! Now I don't kill my battery by forgetting to turn off the headlights.

Well it's more of a chime. I'm glad it's not that original angry buzzing sound. Like a pissed off cicada.

I'd be curious to know what all sounds you can get, to plug into that factory slot. I vaguely remember someone talking about how some older cadillacs had a really cool sounding door chime.

I went and bought one also, for my 86. The chime wasn’t on the 86 and older. But since I added it, it has saved me a couple times of leaving the headlights on.
No way would I throw mine away.
