15 Thor Chalet E450 Ford Park Fuse Problem...Help!!

[Pitorro]

I have a Ford E450 Engine, 2015 Thor Chalet, 31L RV. My Park & Side lights plus my Plate Lights don't turn on. These Lights are #22 on the Ford Fuse Box. I have replaced the 15A fuse,but it also went out (Burnt), twice. Tried a 20A same thing happen. Im no mechanic, but changing a fuse is easy. Brake, Signal and Hazard lights work fine. Can I fix it at home or does it need professional / warranty help? I hate waiting for my RV, they take to long / days in the dealer and I need the RV at this moment. Thanks

Fuse is blowing because there is pa short somewhere in the wiring or a bad lamp. You'll have to find a knowledgeable person to troubleshoot the wiring. Did it for a living a while back and some shorts could be found in minutes and others took a full shift.
