im new on here. i have a 05' F150 and my 4x4 is not working. there is no noise from the transfer case and no light. i pulled my eletronic switch out and tested the wires and there is no power going to the switch. no blown fuses and good relays. what would be the next thing any of yall would check.

 

did you ever find the answer for this? i am having a very similar issue and have asked the same question but not had any feedback either.

 

Check for power at the transfercase motor when dash switch is switched. I think the biggest wires are the motor leads. If no power at transfer case motor, check gem.
