Fuse #14 is the deactivator switch for the Cruise control.
Unlike the 199-2003 MY, where there is a cruise control switch, that operates the servo. The 2004-2008 do not have the servo, due to throttle by wire operation.
The Cruise control is activated, and the PCM operated the Throttle control motor, and the feed back is the TPS ( throttle Position Sensor ).
If the Cruise Control is no longer working, could be the switches or the wiring to the switches.
Do the horns and the other wheel controls ( i.e. radio if installed ) ?
Thinking problem with the clock spring.
Recall 05S28 for the Speed Control Deactivation Switch is not applicable to the 2004 + MY trucks ( unless it is a 2004 heritage or lightning ), no need to worry about that. Engine size does not matter for the Cruise Control, it is only applicable to the Throttle motor and position configuration, still throttle by wire on all engine sizes.
Just thought of something. Did you change the CHMSL ( Center High Mount Stop Lamp ) to a LED one ( like Recon, etc ) ?
If you did this, and do not have the load resistor installed ( or installed correctly ) the cruise control will not work. The system checks to make sure you have brake lamps, prior to allowing the CC to be set. Without the load resistor, the brake lamp to the truck appears to be out.
Sorry it took so long for this to come to the top in my mind.

SOURCE: cruise control will not come on im not sure if
There is a fuse layout in the owner's manual... and on the fuse box lid.
Are you certain it is #20 - and not a 20A fuse?
It is either 15A (blue) or 20A (yellow)
Without a diagram - you can verify all of them quite easily with a simple $4 test lamp from the parts store.
With the key in the ON position test for voltage at both sides of each fuse.
Whichever fuse does not light on both tabs is a bad fuse.
You could have them all tested in 2 minutes.
Thanks!!

There are four fuses that can affect the cruise control. In the underhood fuse panel, fuses #12 & 22, and in the rear fuse panel, fuses #34 & 39.
There are other things that can stop the CC from working, stuck brake light switch, bad vehicle speed sensor, certain fault codes set by the computer, to name a few.

Hi Debbie,
First I think it should be said that whatever is wrong with your cruise control it is definitely NOT caused by a fuse. Fuses do not cause electrical circuits to fail. Failing electrical circuits case fuses to blow.
With that said, there are 2 fuses that affect your cruise control operation:
Fuse #6 (10 Amp) and Fuse #7 (15 Amp), both of which are located in the instrument panel fuse block. Fuse #6 is the power feed to the cruise control servo and Fuse #7 is the brake lamp fuse, which provides power to let the cruise control servo know when you have applied the brake.
