Hey I bought a 1991 m923 a2 and am having issues with all the lights . Nothing works except the front running lights are on all the time. From what I can find, all the previous owner changed was the batteries to a 2 battery system and he put led headlights in . The key pad that controls the lights , lights up red/orange when you push it and if you select any other button it flashes blue a handful of times then back to red/orange. I couldn’t find any fuses or where anything had been messed with . My only guess at this point is the little key pad thing has failed . But I am as green as Grass when it comes to these trucks . Any tips ? Thank you !
