Assuming the signal will come on when you switch from left to right,the flasher itself is probably blown.Get your owners manual out look for signal flasher.It should tell you where it is located,change it out and you are ready to go.Turn signals quit working on my Buick, what%26039;s wrong?
check your blinker relay most times it's in your fuse panelTurn signals quit working on my Buick, what%26039;s wrong?
Some GM models had a recall for a defective flasher switch which will cause the blinkers not to work. You didn't say which year model you had but if it's a 99 or above then it you should check with either GM or a local dealer to see if your car is one of them.
Even if it's not there may be other recalls that need to be performed.
