No Electrical power to T/F motor or switch in dash. All fuses are good, hi/low lights don't "prove out" when starting my truck, test the inst. cluster and they work. Any thoughts on where the issue might be? '05 f150 4x4.
New T/F motor, IWE's are good and vacuum is good, solenoid is good .

 

You checked relays in the underhood fuse box ?.. if those all are good .. shift motor.

 

I have a 06 4x4 on floor with newer actuaters.when your rolling you can hear something dragging up front. So jacking up the front with the truck running the actuators unlock like there suppose to but when it's off the driver side spins easy and turns the axle and driveshaft.but when u turn the passenger side it soesnt want to turn.you have to force it.is that normal. Apparently somehow the vacuum hose came off the passenger side and didnt notice it for a couple days.so now I'm trying to figure out why that sides hard to turn and what the noise is going down the road since the axles aren't locked in while driving.im stumped and any help would be appreciated

 

I am having the same issue. No 4wd high light. Low light comes on. Did you ever find a fix for this? I checked everything from vacuum to tc motor and everything checks ok. Thanks for the help
