ESOF Help!
Ok. Quick rundown. My 99 f350 wont shift into 4x4. Checked fuses, relays, switch, and all the wires I can find in the diagrams. All good. Plug in my auto enginuity and come up with p1828 and p1820for the gem module. My lights flash apon start of the truck but when I ground the relays and the motor switches into high and low, no indicator lights. This thing is driving me nuts! Please help!
