Why does the 4WD dash light stay on while the truck is running?
The vacuum is used to lock and unlock hubs while the truck is running, so any sort of leak can cause a failure to engage or disengage 4WD. If the F-150 or F-250 can successfully switch itself from 4WD to 2WD via the 4WD switch in the cabin, then the vacuum lines are likely not leaking badly if at all.

Why is my F-150 not shifting out of 4WD?
They don’t have a rain shield to prevent water from reaching the IWE circuit and shorting it out. A failing IWE solenoid is the most likely culprit when an F-150 can’t shift out of 4WD. When it shorts, the solenoid fails to release the 4WD actuators. If this is the case, replace the solenoid. Figure 2. A typical F-150 IWE solenoid outlined in red.
