I am assuming you are referring to the head lights. In most cars, the warning buzzer only sounds when all these areoccurring: 1) lights manually turned on, 2) engine is off, 3) door is open. If the buzzer only sounds when these 3 things happen, it's normal.
If this is not the case, there is likely a short or broken connection between the control circuit for the buzzer and one of these sensors. The sensors may be working fine and the connections to other monitoring circuits may be fine which is why it only effects one system. It would be impossible to go into any further detail as to how to locate, diagnose or repair the buzzer control circuit without any vehicles specific information.
If you still get the warning lights for low air, you're good. FMCSA only requires that some warning system be operational.
I recently took thebuzzer box out of my 93 Continental cause it was annoying me with my "Check DCL" light. The box is located just under the steering columb. If you remove the piece of carpeting that is right above your gas and brake pedals. You will see a box off to the right hand side that will have 3 holes in it and a wiring harness with several wires comming out of it. You can disconnect this and that will take care of the buzzer for your "Check Engine" and any other warning lights that come on. It will also disable the buzzer that goes off when you leave your lights on and when your door is ajar. If you do this just make sure to keep a close eye on when you have any warning lights come on.
its brokenthe engine is runningits missing?
This is for a 1993 Chevy S-10 Pickup (caveat- NON expert- shade tree mechanic :)I never found the buzzer- it's 'somewhere' under the dash. My hearing isn't good enough to pinpoint the sound's origin, especially while assuming the obgyn position under the dash. What I want to contribute is, for my car, the "Headlight Warn Buzzer" should, imho,be named- the tail light warning buzzer. Tail lights (running lights, side markers, YMMV :) come on with the headlights, but have separate fuse/wiring. The buzzer is powered by the TAIL light circuit.btw, for instrument lights out, check TWO fuses: The "Inst Light" fuse,and (you guessed it:) the "TAIL light" fuse.Moral of the story- tail lights power much more than just . . . tail lightshth
I had this same problem with my !995 Galant. It turned out to be the alternator.
There are several reasons why a Toyota's warning lights may come on. The lights may come because there is a problem with the engine, low oil, or even bad brakes.
dirty sensor
It is normal if other lights come on at the same time. All of the reminder/warning lights should come on when ignition is in idle (key's in ignition, but the car is not running)
Which lights?
Warning lights on a 2008 Honda Accord include the gas light and the check engine light. There is also lights that come on when doors are open.
It depends on what lights, did you turn on a switch, open a door, If they are dash warning lights, you have a malfunction.
Break lights come on when you step on the break, they do not come on when the head lights are turned on.
