If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

The best way is to find something that is plastic and has a wedge shape, you place this in the top rear corner of the door between the door and frame, once you have the wedge in enough so there is a gap to get the wire or coat hanger in the door you should be able to get to the lock with out wrecking the window gasket or the door gasket.

In most cases, you will wreck the window gasket if you try to access where the window meets the gasket, so it is better to access it between the door and frame.

really tough to do on the net but first we need to know about any codes...

Hold speed control OFF button, and turn ignition switch to RUN position. CRUISE indicator should flash once to indicate successful entry into self-diagnostic mode. If CRUISE indicator does not flash, start procedure over. If CRUISE indicator still does not flash, repair system by symptom there might be some switch concern

If CRUISE CONTROL indicator flashes once followed by 5 additional flashes, replace speed control servo/actuator.

Release speed control OFF button. Within 5 seconds in entering self-diagnostics, press speed control ON button. Press remaining speed control buttons in the following sequence; ON, RES, COAST and SET/ACCEL.

As each button is pressed, CRUISE indicator will flash.

Wait until indicator light goes out, then press next button. After sequence has been completed, indicator light will flash to indicate test passed or failed. With the codes we can then better diagnose your concern

Immediately after static test has passed, actuator performs a dynamic test by automatically operating throttle .04-.40" (1-10 mm). Observe throttle movement to witness any sticking in cable or linkage. Ensure throttle returns properly. Turn ignition switch to LOCK position. If self-diagnostics do not pinpoint fault there is more we can do but tough over the net

I find these diagram to be helpful when wiring a trailer or vehicle.

You most likely have a bad spark plug coil and or plug. First recomendation go to your local parts store and have them put a code reader on it. It should tell you what cylinder is missfiring under load. Once you identify replace the coil. Cost $45-$60. Also replace the plug. After this you should be back in business. This is common with the 5.4L engine. Depending on the cylinder involved the coil can be difficult to get to so take your time. Definently and easy do it yourself repair.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

If the front axle does not turn, the cause generally has to do with the Vacuum disconnect motor on the axle ( Item #10 in this picture ) :

Close Up :


The vacuum disconnect motor is operated by the vacuum axle disconnect solenoids on the firewall


You can test from here with a vacuum pump ( i.e. mightvac ) to see if the vacuum lines to the vacuum disconnect motor are good.
The pink vacuum line is 2WD operation, the Light Blue vacuum line is 4WD operation.
If the vacuum lines test good from here to the disconnect motor, and applying vacuum locks the front axle, it is either the vacuum solenoids, or the vacuum reservoir behind the battery, or the vacuum lines to the solenoids.
The solenoids have + VDC all the time, and the GEM applies ground to the correct solenoid to engage or disengage the front axle.
