truck won't go inito 4WD after leveling kit

I had an autospring 2" leveling kit installed on my 2006 f150 and now it won't go into 4WD. I flip the knob over and nothing happens, no 4WD light or anything. I am thinking its a pinched or broken vacume line. Has anyone else had this happen?

Thanks

take a hammer and lightly tap onto the shift motor on the back of your transfer case....then shift into 4x4

the leveling kit install should have had nothing to do with your IWE's.

Check your vacuum lines at the hub and follow them up, into the engine compartment. The installer may have disconnected them and failed to reconnect them upon completion. There is a joint in the line, just behind the plastic wheel well cowl. It is a few inches above the frame.

Is the box on the drivers side near the front with 4x4 written on it the ABS system? One of the lines that I thought was a vacume runs from the drivers side hub up to this then it isn't connected to anything and I don't know where it goes. The other vacume line from the drivers side hub runs back to the passenger side and looks ok as do the rest of them. The fuses are ok too, I will probably take the truck to the dealer. They guy that installed the leveling kit said he put it in 4WD afterwards and it worked.

That line up by the ABS block on the drivers side that is a hard plastic line that has a curve to it is supposed to be not connected to anything, its the vacuum vent tube for the 4WD actuator at the wheel.

Read this for more info on the 4WD not working. Especially before you take it to the dealership and dish out money.

Please tap the motor (small windshield wiper looking motor, bolted on to the top of the tranfsercase, crawl under the cab, drivers side) like Tylus suggested.
Guys, he's not getting the 4x4 light to come on when he turns the knob. The indicator light is in no way connected to the IWEs or the vaccume system. Light comes on when the motor shifts.
