I'm sure this has been answered before as I am a long-time Ford owner and fan and having been in the "biz" for years this problem rings a bell. One of my dealers owed me a favor so I took my new toy in for a full detail (i.e under hood steam clean,interior steam clean, exterior detail). When i dropped it off everything worked on the truck. After picking it up I tried the rear window and no luck! I know the motors go bad but what are the chances?! It seems like there is no power going to it as neither opening options work. So I checked the fuses in the inside block, is there another one under the hood? Any insight would be appreciated.
