Ford Thunderbird Owner's Manual page 174

Always replace a fuse with one that has
the specified amperage rating. Using a
fuse with a higher amperage rating can
cause severe wire damage and could start
a fire.
4. Close the cover.
Even after you replace a fuse, it may continue to
blow if you do not find what caused the
overload. If the fuse continues to blow, have
your electrical system checked.
Circuit Breakers
If you need to check a circuit breaker that is on
the fuse panel, see Checking and replacing fuses in
this chapter to find out how to locate the fuse
panel.
Circuit breakers will reset themselves and allow
the electrical parts to work again once the
overload on the circuit is removed. If the circuit
breakers continue to cut off electricity, have your
vehicle's electrical system checked.
Diagnostic equipment is needed to check circuit
breakers. Refer to the manufacturer's
instructions.
If you replace a circuit breaker, use one with the
same amperage rating. To remove a circuit
breaker mounted in the fuse panel, grip it with
your finger and thumb and pull it straight out
of its socket.
