Greetings All
I have a front camera that has never worked since I bought my truck. I did not buy it new. I would like to know three things:

1. How can I diagnose and pinpoint the camera as the faulty item (rather than some other device/wire) ?
2. Can I remove and replace this camera myself?
3. How can I find the CORRECT replacement camera among the many available?

2016 F150 4WD 3.5L EB Platinum with all available options installed. And BTW, the rear camera works fine on the display screen.
