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
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.
You probably have a low refrigerant level.
There is probably a short in the wiring.
Because when a light bulb is tightened the stuff inside squashes then snaps, causing it to blow.
The pressure of the sun causes the wind to blow.
The circuit is shorted. ie. the positive side is directly connected to the negative (ground). If the fuze didn't blow, it would heat up and possibly start a fire.
