Fuses blow because of a over-current (short circuit) or over-heat condition. Look for a short circuit in the tail light circuit. It is also possible that the terminals at the fuse block are corroded, causing heat, which might be causing the blowing out, but highest probability is a short circuit.
A wire is shorting to ground.
The 1998 Nissan Frontier is wired so one bulb indicates braking and parking light use. This is accomplished with a double-fliament bulb. The inherent advantage/flaw in this design is that one filament can blow while the other remains functional. This can be confusing when attempting to isolate and replace the defective bulb.
A dead short to ground.
Probably the wrong voltage
you need a new blower motor resistor
Tail light assembly short
You probably have a low refrigerant level.
Because when a light bulb is tightened the stuff inside squashes then snaps, causing it to blow.
Probably have a short in tail light or license plate light. It could also be a bad bulb. If bulb, see sources and related links below for bulb information.
There is probably a short in the wiring.
The pressure of the sun causes the wind to blow.
Short in the courtesy light receptacle, wiring, or the switch. Can also be a corroded receptacle.
