All the lites work except the front head lites will not stay in the on position. Front head lites only flash when the horn is sounded!! when I use the on and off switch on the legacy remote for the front lites no results. any suggestions??
This does sound strange. Just in case there is any terminology confusion here, is there any chance that you could post a video, photograph or even a diagram that shows which lights are operating, and when?
Another issue that needs to be checked is that there are different reset codes for different diesels engines. R2LC, older before Legacy, boards had (16) different reset codes. You noted a reset, which required a code associated with the specific engine, be sure it is the correct code. Wrong reset code can be an issue. If you posted the model number, it would help with the research and trouble shooting. You need to be sure all programming is correct before you start swapping wires. IMO.
