Owners/service Manual problems of the 2008 Ford Expedition

My truck was put in park and I couldnt put the car in gear. I was stranded with my family for 1 1/2 . I had to do research so I went to the internet on my cell phone and found out that it was the break light switch. I also read the manual and it said to replace the fuse . I did that and it still wouldnt go into gear. I had my wife stand in the back of the car while I depressed the brakes and the light wouldnt go on. After reading on line someone had mentioned to go under the dash board and giggle the switch by the break peddle. I did and started the car and thankfully the car was able to go into gear. I had went out this morning and im still having the same problem. I jiggled the switch again by the break peddle and it worked again.
