2001 Ford F-350 Super Duty Lariat 7.3L 4X4 Inop
Hey all. I have a 4x4 that does not work. It has c1728 code. I have replaced the switch, because it tested bad. I checked the vacuum to the front end, it holds. The vacuum switch tested fine. I can command the gem module to turn on the light for the 4x4 system...
