I have a 2006 GMC 2500. The problem I have now is dimming of the DIC and mirror display. I can be driving on a bright sunny day, and at any time the DIC will dim. The mirror temp and compass display will also dim and will be unreadable it is so faint. The two displays will dim at different times. I have auto-on lights and daytime running lights.Is this related to the cold solder issue I see in other topics?
Thanks again!
