Hi. The buzzer when I leave my lights on does not work. It's annoying because many times I've forgotten to turn off the lights. It also doesn't sound when I leave the key in the ignition.
How do I fix this? I thought it was the buzzer box that is near the brake pedal under the steering column. I replaced it with another used one but still no sound when I leave the lights on and take out the key.

Thanks

Here are the pages from the 94 manual, maybe they’ll help. If the seatbelt alarm also doesn’t work, I’d be looking for a power issue or maybe loose ground (by the data link connector under the dash).

Very common for the door jamb switch to be bad, totally poor design. Also check your brake lamps, same fuse if I remember correctly.
