This vehicle is a Denali, so it has all digital lighting. Right directional start off normal then speeds up.

Hi,

Does it do it regardless of the direction? Also, if the light speeds up as you mentioned, that is an indication of bulb failure. Have you checked to see if there are any not working?

Let me know.

With the blinkers going can you check to see if the front and rear directional LEDs are working? Chances are you have a right rear LED control module that is out and needs to be replaced. Here are the blinker wiring diagrams so you can see how the system works. Here is how the LED module is replaced in the images below. Check out the images (below). Please let us know what happens.
