most likely is a faulty chime switch,or a faulty ignition switch
Yes, the ignition on a trailblazer can cause head lights to work improperly.
It enables you to see if all the warning lights are functioning properly. Since they're just ordinairy light bulbs, some of them could stop working over time.
It could be a way of saying "I'm working fine and starting now because you told me to", I've been in a few cars that do that. Look out for warning lights on your dashboard though because the sound could accompany a flashing warning light, the user manual/booklet that came with the car will have all the details regarding what you need to do when warning lights are displayed. The only other thing I can think of is that perhaps your doors aren't closed properly, the boot might still be open or your seatbelt might not be on.
look for the problem in the ignition switch.
If you are wondering why this happens, it is completely normal. When you turn your key all the way to start the car, all the warning lights will come on do perform a lamp test. Also, the computer runs a quick test on all the sensors in the car and on all the lights on the dash to make sure everything is operating properly, once you start the car, these lights should all go out. If there are lights remaining lit on your dash, it may mean that your car needs to be serviced, always get warning lights checked if they come on while the car is running. Hope this helps!
The red water warning light is an indication your engine is overheating. The red battery warning light is an indication that the charging system is not working properly.
The warning lights on a 2006 Volkswagen Jetta can indicated problems ranging from incorrect ignition timing to low air pressure in the tires. An OBDII code reader can be connected to analyze the problem.
The warning lights on a Honda Accord are the same as the warning lights on most other cars.
Dashboard symbols and warning lights are a fool proof way to help a car owner keep their car running properly. A cars symbols will have different meanings. Check your manual for each lights meaning.
By "OFF," I have to assume that your question means that the ignition switch is "ON", but the engine is not running. IF that is what your question means, then the reason the engine warning lights turning on is that the manufacturer designed the system that way to show you that those warning circuits and lights are working, and ready to warn you after you start the engine, should there be a failure in one of the systems they represent.
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)
The red oil can warning light is an indication the oil needs to be checked immediately. The red battery warning light is a indication the charging system is not working properly.
