I have a 2021 Traverse and recently the driver side blinker started blinking faster than normal. Then out of nowhere it started working. Now the blinker is blinking fast again. I checked all of the bulbs and none of them are blown. The 4 way flashers also work properly. If anyone has any suggestions of what I should check next, that would be great.

Thanks,

Ryan

 

Are they factory style bulbs, or some aftermarket "upgrades"?

check the bulb socket and wiring. You could have some corroded contacts, chafed wires etc.

Try swapping out the fuse.

If all else fails, invoke your warranty.

 

Yes they are factory bulbs. I checked the socket and there wasn't any corrosion. I swapped the left and right front bulbs and that didn't make a difference.

 

yup, invoke your warranty, one of the best thing about having a newer car.

 

Hey Camarodude: I also have a ‘21 Traverse with the same problem (right side). My other ride is a ‘13 Camaro 2SS. Small world!

I would really appreciate any info you could share on this issue. I can’t even locate a fuse for the turn signals! If you could share their location I would greatly appreciate it.

Many thanks,
Stan

 

Turns out my tail light had water in it and it caused some of the LEDs to be bad. I had to replace the whole tail light assembly.
