2000 F350 stuck in 4 low. Help!

[jobar]

For the past 2 winters we have had to get out & manually lock the hubs in to use the 4WD as the switch inside does nothing. At some point the 4WD light came on & has stayed on. Got under & manually put it back into 2WD. Took it to have new tires & front end alignment done & when I picked it up it was stuck in 4 low. Those &#@+* claim it was in 4 low when they got in it. Obviously, think I'm stupid & don't know when my truck is in 4WD. Drove it home at less than 25 mph & have spent 2 days trying to get it back into 2WD. If I turn it manually then the motor won't go back on cuz it's in the wrong position. Replaced both relays and nothing. Need to drive this thing out of town next week & am at a loss what to try next. All suggestions welcome!

Im guessing you have the electric transfer case (knob on the dash?) Will it go into regular 4x4 high? or 4 low only? I would look into checking the tranfer case shift motor, and possible replacing it... that could very well be your issue if you have power going down to it and nothings happening.

Rock Auto has them for around $100

Yeah, it has the knob on the dash, but it doesn't do anything at all when you turn the knob. So I have no idea what they did at Conrad's that caused it to go into 4 low. Replaced the motor already & nothing,

Well, ended up taking the motor off the transfer case and applying power using the battery in one of our cars. Turned it right around. Manually turned the motor to get it in the right position and put it back on. So now we know that we're not getting power to the motor & have to trace that back to see where the breakdown is. Thanks for the suggestions!

check for power at the relays and just keep following it back to the switch. sorry i can't tell you the actual wire routing
