It was the relay, #49, on the fuse box inside my truck. Everything works fine now. I have returned the camera, unopened, and gotten my refund. So, things are ok. Hope this helps.

 

Thanks for this, from time to time my front driver or passenger window won't go back up until I swear at them a few times. Both front switches won't work when this happens, so I'm thinking it may be the relay not the switches. After looking around, I can't find a difinitive part number for the #49 relay. Do you have a link or part number I can use?

 

I took my truck to the local mechanic. Here is what he put on the invoice, (I think, his handwriting is bad).
Part number 20976, Accessory Relay. Seemed kind of expensive at $38. but it was a shop. Lot less than Ford, I'm sure.
I hope this helps. I know how frustrated and worried I was.

 

Thank you, "Ford relay 20976" in the google bar works, doesn't look like your mechanic upcharged you much either.

 

They are known as an honest, trustworthy and dependable shop. Don't have to use them much, but when I do, I am thankful for them. Hard to find people like that.
Hope the part works for you. I was almost ready to swap out the camera, to the tune of almost $300, until the windows went out. Good luck and let us know if it works.

 

I have a 2012 lariat that the power windows and rear camera both quit last week. After Beining out of the car for several hours they all worked again. A week later it happened again but would not start working again. Changed the 49 relay and everything is working again. This same relay went out on another circuit a while back and I had bought an extra.
