Hyper turn signal

My wife’s 2007 Buick Lucerne’s directional signal is acting odd… When you turn it to the left-hand blinker, the pace is not the normal factory pace. After two or three cyclse it then starts blinking on and off VERY quickly, like those blinkers you see on junkers periodically. The right blinker is normal pace as are the hazards lights. I am looking for potential causes before I bring it in for repair. I can’t say anything trigger it, other than I noticed it after a car wash. Electrical problems are not my thing.

Are the front and rear bulbs actually working? This is usually an indication that one is out.

I just checked, the rear doesn’t flash… so the simple fix is new light bulb?

Yeppers. Replacing the bad bulb should fix it.

Thanks guys… I am buying a new bulb and replacing tomorrow. All these years, and I never knew this was what happens when they go out.

I agree with the other guys. The only thing that concerns me is that it flashes normally with the first 2 or 3 cycles. The bulb will probably fix it but if it doesn’t you may have a poor contact at the socket.
