My F150 Lariat 6 disk changer gave error messages, continuously cycled the device, and only the radio would work. I prepared for the worst, expecting that it would need replacement. That is until I read this post and tried the fuse pulling trick suggested by kb8rhu. I was so elated that the fix was that simple.
Imagine what a gravy job that would have been for a dealership. That would have been a 1000% profit repair,not the regular 300% they usually get.
So, many thanks to all who offered other suggestions as well. As happens so many times in life, the solution to most problems are usually very simple.
