Had a funny day today. First a bird managed to **** on my hood, so I jumped in the car and ran the car through a quick car wash, since I wasnt home. Well, I forgot to lower the aerial because I never run a car through a carwash, and I bent it back far enough to give it a cool 45 deg angle. I disconnected the plug from it to keep it from powering up, but just curious about the fuse location.

 

F4 in the Auxiliary Junction box behind the rear seats

 

Make sure that your radio is off before you remove the fuse, which is in the fuse box located behind the vertical cushion in between the rear seats. That upper cushion is secured by friction-fit pins at the top that will release with a sharp pull towards you. Put your hands on the sides of the cushion near the top and sharply pull it towards you to release it. When the top of the pad is free, lift it up and out. The auxillary fuse box is right there. Pull the 10A fuse in F4. There should be a fuse puller tool in the bottom of the fuse box.
Reinstall the cushion and have a beer!

Watch this:

Disregard the advice about removing Fuse 19 because it applies to XKR models with an active exhaust. Your XK does not have an active exhaust.

 

I think you meant F4.
