Cadillac 2007 DTS - Manual (Page 444)

Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating. If a fuse should
blow, see your dealer for service immediately.
If you ever have a problem on the road and do not
have a spare fuse, you can “borrow” one that has
the same amperage. Pick some feature of your
vehicle that you can get along without — like the
radio or cigarette lighter — and use its fuse, if it
is the correct amperage. Replace it as soon as
you can.
The fuses are located in two fuse blocks,
one located in the engine compartment, and the
other under the rear seat. If a fuse should
blow, have your vehicle serviced by your dealer
immediately.
Underhood Fuse Block
The underhood fuse block is located on the
passenger’s side of the engine compartment.
Remove the fuse cover and secondary service
cover to access the fuse block.
