Hi Tom,

it sounds like your 4wd control module set DTCS have your trouble codes cleared and it should work fine if not we are going to have to check power and grounds at the 4 wheel drive actuator and Hi and LO switch, Check your fuses first then check for power at the 4 wheel drive actuator and ground at the switches, I'm attaching 4 wheel drive schematic and wiring diagrams below. Let us know if this information was any help and if you found the problem and if you need any more help.

Thank you
Joe Terwilliger
