Got an '04 f150 that doesn't seem to be working in 4wd. My indicator light will come on but i don't get any rotation from my front tires. Any suggestions?

 

Are they vacuum operated(auto), may have the vac lines busted or leaking.

 

Auto yes

 

is your front drive shaft turning? Put your phone under your front drive shaft and take a video of you moving the truck back and forth while in 4wd. If it's not Turning then you have a Transfer case problem. If the front drive shaft is Turing then it's a problem with the front axle
