Blinkers is flashing real fast. Cked fuses and that is not it . What else could it be?

Usually when they flash fast means a bulb on that side is bad.

fast flashing inside indicator lights usually mean a dodgy earth wire. start the car, put on the indicator, get out and have a look at what the outside lights are doing, check both sides. You may find the stop/tail light also flashes dimly with the indicator, if so then it is a dodgy earth wire, it may be touching another wire or be loose. check it out and get back to me. I am in the UK and I think our lights are a little different, but give it a go and see what happens

Look in your manual find the relay pull it and take it to a parts store and check it.

most blinkers uses relays, and when they flashes fast one light is out, but you replaced your burnt bulb might be a bad relay.

Check the switch

Have you removed the bulbs and checked them and the sockets for corrosion? Also make sure they are locked into place properly. Another thing is to check the flasher relays under your das by the fuse box to make sure they are properly seated.

The blink rate of the flashers is governed by the electrical load applied by the indicator bulbs themselves. If a bulb breaks or becomes disconnected the load drops and the blink rate increases as a result. Check out the wiring to the front indicators, the socket connections and the bulbs to ensure that they are working.

you have a bad brake light switch

The buzzing sound is probably your relay. It is in your fuse panel and it is what controls how fast your blinkers flash. It is usually a round plastic thing in the fuse panel. and you replace it just as you would a fuse just pull the old one out and push the new one in
