Hi, I have a 1999 Expedition Eddie Bauer with the 5.4. It seems to be locked in 4wd, the ABS light is on, and sometimes when I start the truck the windshield wipers and washer pump will come on for a few seconds. I hear this is probably the GEM so I took it out and cleaned it, pulled all the fuses (all good) and replaced. There is talk of leaks causing issues but I could not see any water in the GEM or fuse box. I have been trying to figure out what actuates the front hubs (are they locked all the time?). I guess the next step is a new GEM and if that doesnt work I guess I will be looking into a new transfer case. Just hoping you guys might have some experience with this situation and might direct me better than a mechanic just quickly saying that I need a new T-case. Thanks for any help.
