Fuse 14 keeps blowing
It's an 07' F150 with the 5.4 in it. Everytime the fuse is replaced it blows. Sometimes the fuse blows as soon as it makes contact other times it could take a few mins for it to blow, and times as soon as the truck is put into gear it blows. It's a super crew cab 4x4 if it makes a differ. Any ideas as to what could be the cause would be greatly appreciated. Thanks in advance.

Check for short/wiring.
According to user manual fuse 14: Back-up lamp and Daytime Running Lamps (DRL) relay coil, A/C pressure switch, Redundant speed control switch, Heated PCV (5.4L), Trailer tow back-up lamps relay coil, ABS, Reverse park aid, EC mirror, Navigation radio (reverse input).
Does it pop out when you put in reverse gear?

easiest way to check heated pcv is just unplug( see if you stop blowing fuse. If so? Just leave unplugged until you have chance to order/replace.
I have a thread somewhere that covered my experience, with. Part number. And info.

THe OP gave you list of items to check. I’d be betting on the heated pcv or a trailer wiring issue.
