The turn signal switch may fail causing the hazard/turn signal flasher to continue to click even when the turn signal switch is off. Replacing the faulty turn signal switch will commonly correct this condition.Google+

Clicking noise most like the hazard signal randomly clicks for long and short periods of time for no apparent reason and is extremely annoying. Replaced the relay switch but still have the problem.

Just like my daughter's 03 Grand Am, my alero will sound as if turn signal is on when it is not. I am not sure whether it is the hazard switch or the turn signal/w.wiper unit that needs to be replaced as was the case with the Grand Am. Annoying. Too many of us have the problem for GM to look the other way as it is obviously a problem common to alot of vehicles.

Radon Clicking sound of flasher/turn lights when not engaged.... Me Too!!!!!!!!
Did Try checking the fuses and found the fuse for the turn lights would when removed stoep the noise, that would leave the turn lights in operable.
Also if pushing in slightly on the Hazed button not to engage it but lightly it too would stop the bzzzzzzrrrrrrrrrrrrrrrrrrrrrr. I Rather just play radio louder.!

My turn signals will not be on, but the clicking is incessant. My turn signals don't actually flash any lights when this happens, but it's really annoying.
