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.

    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.

    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.

    I had the same issue with the clicking noise after the blinker is turned off. Now the blinkers are only working half of the time. I will try to replace the blinker switch as recommended.

    Clicking noise like a turn signal or flasher, very random. I've investigate and concluded that replacing the hard to get to Hazard switch will not address. My trusted mechanic says he has seen this on numerous Aleros of my vintage and the issue is within a harness that is inside the steering column, which somehow is sending voltage to the flasher circuit. The harness (which likely has some electronics/logic) is very expensive, couple hundred $$and then costly time to access& replace. I cant justify on a car that is likely worth $2500 so I have not pursued (at this time) as while very annoying, seems to work at least for now.
