Is it an electric like buzzing not too loud, or more strong?
I had a problem with the vacuum pump which is located on the left side, a little bit right, below the water coolant expansion tank, it is white and has the size of about 5 cm in length and about 2-3 cm diameter, if you pull down both little black rubber harnesses and it stops, then it was a vacuum pump. Made a quite loud buzzing sound in my car after I stopped the engine. I'd give it a try, only 10 seconds to do the work. If this is the problem you can get one free from a wreck or buy a used one, the don't really go bad too often, I would not buy a new one. But also read the other solutions as this was only my case.

2002 dodge Grand caravan lights will not turn off

You have a relay that's sticking. Open the hood, then fuse box. Turn the lights off, whichever relay is buzzing replace it (they pull out like a fuse). Usually they are around 15-25 bucks at the local auto parts store. Hope that helps.

2008 Rav4 Check engine and oil lights on ignition off

You have a stuck relay. It will be in the fuse pannel under the hood. With the car off open your hood and find the fuse pannel the best way to find it is to put your finger on the relays and feel them. One will be buzzing. You will have to get another one from your parts store and replace it.

The car will not start anymore and is buzzing without the key inside like the battery is dead but I put a new battery in and it does the same thing and will not start.

Check your relays. Generally when a realay is bad, it will make a buzzing sound, you can find your realays under the hood.
