Hi, i have a 2000 blazer and my turn signal keeps on making the noise after the lights have stopped flashing, everything works properly except for this annoying audible noise,

The best solution you'll get from b ooks at www.reliable-store.com

These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicles cars, atv, trucks. forklifts, boats, excavators etc

Check if your emergency flashers still work. You possibly need a new flasher. Some cars have separate flashers for turn signals and emergency flashers, but some they are both together. If your emergency flashers still operate leave them on and find the flasher (follow the clicking noise the flasher makes) and see if there is another flasher right next to it. swap with the emergency flasher and see if your turn signals work again. If so, replace the faulty flasher.

you are describing a typical turn signal switch problem, all those systems run through this switch, its about a 110 dollar part

can try to check the bulb first then the fuse mate. then check the fuse for the horn.

try replacing the flasher...

the brake element of the bulb and signal are the same look for a bad or brocken ground on the socket

The vehicle you are working on may or may not be affected by this recall. Contact the vehicle manufacturer for clarification. hope this solves your problem.THANK YOU

most likely its the turn signal relay. which is under the hood. in the fuse box. also make sure ur running lights are working if they are connected to the turn signal.

First thing i would do is chg. the break light switch, and make sure to chk. all grounds around tailights, sometimes if there is a ground problem it will travel back thru the hot wire to get a ground, witch in turn makes everything go wackey.

We had the same problem. Hubby replaced the multiswitch and that fixed it
