Hello. I've got a '92 Honda Civic.
A few days ago I drove my car to the store. Fine, I just switch the key and go in. When I come back and start my car, I hear a strange vibration sound. It's pretty loud and very annoying.
I had my light switch on "Off", which activates all lights but my dash light. When I turn the switch the sound stops. This sound is only when I have my light switch on "Off". It stops right away if I turn the switch.
I really want to fix this somehow because some day I will forget to switch off the lights before I leave the car, leave the lights on over night and wake up to an empty battery. And that really sucks.
If you have any suggestions on what this is and/or how to fix it, please post.
