if its like the late 90's Monte Carlo's . The turn signals get their power through the hazard switch. It will most likely need replace.

Early to mid '00's Monte Carlo's and Impalas have hazard switches that are fairly prone to failure, some reports as high as 60% OE failure ratings. The turn signals are routed through the hazard switch, and when it goes, they both go. Aftermarket replacements can be found on eBay for under $30.

Gm needs to build better units, Have you noticed how many turn signal problem posts there are online?

Isn't your car under warrenty? Check for recalls.


Nothing needs to be replaced. The problem isn't exclusive to GM; it is all vehicles with a flasher switch mounted on top of the steering column. Over time, dust builds inside the switch and pretty soon, the ground gets gummed up. Spray WD40 or better yet NAPA's "Brake and Electric Motor Cleaner" down the flasher switch hole; work the switch up and down several times and everything will work fine again. If the flashers regain power but the turn-signals do not, spray some cleaner in the directional switch hole as well. It works like a charm!!!


Actually the wiring is frayed a bit so if you wiggle it up and down or do what mechanics refer to as the "Beezer Boy Shake", you should be in business.
