hey guys need help bad no 4wd in my 2005 6.0 fuse under dash good, no dummy light on dash, how can i troubleshoot this? please help im looking at 24 inches of snow tonight and i live in delaware not maine anymore people freak here and its horrible.

try manually locking the hubs, check for vacuum problems. does the light on your dash come on? Do you have any heater control issues?

do you have manual hubs? or is it that the transfer case isn't kicking in? have fun in the snow haha they are calling for close to 3ft here . tow haul is really nice in the snow just tap the brake and it will down shift with alot of engine braking.

maybe its just the light malfunctioning. Have you tested to see if its in 4x4?
24" of snow! Be sure to manually lock the hubs for true 4 wheel drive, but with that much snow clearance is going to be the issue and 4 wheel drive isn't going to help much. Better get where you want to be for awhile and camp.

Like the guys are saying - manually lock 'em - then turn your wheels on pavement all the way one direction with the break on, EASE off and it should chatter. If it doesn't.....well on of the Tech's on here will need to help ya cuz you have problems.

when my 4x4 broke on my 2003 f-350, it was a lose power wire. check that.

i have manual hubs, the light does not come on, but it does come on when the key is cycled through acc upon engine start up i can lock the hubs in all day long but if the t case doesnt engage they arnt going to do much

Understood Matt - we'll see if someone can help ya out.

well then it seems like its time to start tracing wires... check to see you you have power to the switch, power out of the switch, power to the tcase, ect...
