Hey guys, I need some 4x4 help! I have a 2007 5.4 supercrew and my 4x4 does nothing no light on the dash or click under the hood. my question is, where are the relays and fuses I can check? and does anyone have a crossover number for the relays so I can get some from napa if needed? also I tried hitting the transfercase motor with my wife changing the dial from 2 to 4 hi but no luck. any other ideas of what to do would help too.
