IF this is a case that the IWEs will not disengage, it could be the IWE solenoid or the vacuum lines to the IWEs. Could also be a problem with the vent lines from the IWE ( the other vacuum line that runs up into the engine compartment, and just hangs there ).

This is the block diagram of the vacuum lines for the IWE ( not actual routing ). You can use a vacuum pump / gauge to see if the lines will hold vacuum. Don't be surprised if the vacuum lines test OK, there is a TSB on the IWE solenoid where it could ingest water, and allow water in the lines, which will not keep the IWE gears disengaged.

Ford does not have a vacume diagram for this system , the vacume has only two lines, one from the engine to the solenoid and one vacume harness that goes from the solenoid to both front wheel ends (hubs) Make note that vacume is supplied to the Intergrated wheel end(hubs) only when the truck is in 2wd and vacume is released in 4x4. So with out vacume supplied the wheel ends are engaged. Thankyou please rate this answer for me Have a good one RJ

Ford 2001 F150 will switch in and out of 4 wheel drive with selector switch but will not unlock the hubs.

The front hubs are activated with vacuum. You have a vacuum leak or bad chech valve in the line. Check the lines that are near the firewall and see if they are ok.

The air flow vent is stuck on defrost mode. when i switch to a/c or face/floor no air is directed out. the fan seems to be working fine

The air direction is vacum controlled. If you have 4X4 and ESOF ( switch in the cab) then you need to inspect the vacum lines that go to the hubs and possibly the hub seals. "default" position for air flow is the defrost position. If you DON'T have 4X4, and it's a diesel engine, inspect the vacum pump, If it's a gas engine then look at all the vacum lines from the intake manifold for a leak.

My 2001 ford F150 is leaking water from above the trans

First off, is this water or antifreeze? If it's water it could be coming from the heat/air conditioning. If it's antifreeze, it's probably either a heater hose or the back of the intake manifold.
