Remove the switch connection which has a vacuum harness with 4 ports that plug directly into the top of it. (The switch is keyed so it can only fit one way.)

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.
