Your turn signal lights are not working but makes a buzzing noise when engaged the light comes on panel and vehicle no flashing you have 2000 Chevy Impala?

The buzzing sound in your 2000 Chevy Impala with non-functioning turn signals, along with the illuminated turn signal indicator on the dash, strongly suggests a problem with the flasher relay. The relay is a small electrical switch that provides the intermittent clicking needed for the turn signals to flash. The buzzing is the relay attempting to function but failing.

Here's what you should do:

1. Locate the flasher relay: This is usually located under the dashboard, often near the steering column or fuse box. Your owner's manual should have a fuse box diagram showing the location. It's often a small, square or rectangular component with a socket.

2. Replace the flasher relay: Purchase a new flasher relay for a 2000 Chevy Impala. It's inexpensive and readily available at auto parts stores. Make sure to get the correct type; some relays are specific to certain functions (e.g., turn signals vs. hazard lights).

3. Installation: Simply unplug the old flasher relay and plug in the new one. Test your turn signals immediately.

If replacing the flasher relay doesn't solve the problem:

* Check the bulbs: Burnt-out turn signal bulbs are a common cause of flasher relay issues. Check all front and rear bulbs.

* Inspect wiring and connections: Look for any damaged, corroded, or loose wiring in the turn signal circuit. This can be more challenging and might require some electrical knowledge.

* Check the turn signal switch: A faulty turn signal switch (the stalk on your steering column) is another possibility. This is more complex to diagnose and replace.

* Fuse Check: Although less likely given the buzzing, check the turn signal fuse in your fuse box, it could be a failing fuse that is still making some contact.

If you are not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic.
