I have a 2018 Suburban Premier and upgraded my cluster. Bought a cluster and sent it out to WAMS for reprograming. Opted to enable the HUD in case I decided to do the HUD retrofit in the future. Now my forward collision alert is not working. Wondering if by having them enable the HUD it caused the Front collision lights not to flash. Has anybody done the same upgrade and enabled the HUD option? If so is your front collision lights still working?

 

maybe they didn't know you had that option and put in the wrong programming. I'd call wams.
