Rear Indicator Warning

[psmack2116]

Hey Group,

 

I'm having some issues with my rear blinkers working and not working lately.. its on a 2014 GMC Sierra. A few weeks back I noticed when it was real cold out that my indicator warning came on.. Thought it was a burnt out bulb or something like that.. Get to work and check.. well all the lights work.. Then on the way home the other side goes out.. Get home and check and its working.  This process has been going on for about 3 weeks now. I found some info on youtube about cleaning the wiring harness under the rear bumper, but it was for a 2012 truck and its been so cold I haven't been under the truck to look and see if the same connection is on mine. The one mystery is that the bulbs are fine, they will work for part of the day, then they will go out.. then on the same drive they will work again.

 

Any suggestions or tips would be great!

 

Thanks,

 

Mike
