HELP!! 4x4 not working!!
I have a 99 f250 I recently was driving down the road front drive shaft came out and busted a suncoast tranny,transfer case and tranny wiring harness. I got new tranny and transfer case I got a harness out of the junk yard that matched my old harness got it al put back together and everything works except the four wheel drive.I have 6v at the selector switch and power at the relays but nothing at the encoder motor.Not sure what to check next I have also check the fuses and everything is good. So if anybody could help me out on what to check next that would be great thnaks for your time Brandon

Is it a electronic shift on fly or manual select 4WD? If electronic, does your A/C work correctly or does it only blow thru defroster vents? If so, you have a disconnected/broken vacuum tube to one (or both) of the front wheels.
