4x4 doesn't work

[ThisGuyUKnow]

so we went to go play with the flex and the front wheels don't spin like at all. at first we thought we were mistaken so we drove straight into a dirt mound and confirmed it the rear wheels spin but not the front. the lockers were on but no fricken' power was going to the wheels.......AHHHHHHHH:banghead: so now i got a new frustrating project to work on. ahhhhhhhhh!:banghead:

Don't know if you have fixed this but I had a similar problem. It turned out that my vacuum lines were cracked. There are some hard brittle plastic lines that go from the vacuum canister to the steel lines that go to the transfer case. I replaced the lines with 1/8 inch vacuum line and all was good. If the light turns on in the dash then all is good. If you have the front axle disconnect then that has to work first before the t-case will switch.
