Nissan Xterra Blower Motors

Nissan originally marketed the Xterra for the 1999 model year. The manufacture of the compact Nissan Xterra SUV continued through two generations through the 2015 model year. Even with continued reliability, parts such as your vehicles blower motor may ultimately need replacement.

Why would the Nissan Xterra blower motor just stop working?

There might be a couple of reasons why the fans blower stopped functioning on your Nissan. One indicator is the relay. Your SUVs AC/heater blower is not going to operate if the current from the relay is completely stopped. The resistor could be another possibility. The resistor resists excess current from the electrical system. The cars blower might have been zapped with too much current that destroyed it as an effect of a malfunctioning resistor.

Does a blown motor relay fuse indicate a serious problem?

The Nissan Xterra blower motor relay acts like a switch that comes on when it receives a message to reduce power or circulate the cars airflow as it is driven. It could cause a spike in the current and overwork the system when not working properly. Thats why the system, or its fuse, will shut down. Its a mechanism to protect itself from damage. It could potentially lead to more serious electrical issues if the blower motor relay isnt replaced in a timely manner. One such problem could be melted wires or the relay itself. However, when it first happens, it can be a smart way to learn about an issue before it becomes too serious.

Are the Nissan blower compatible between 2004 and 2009?

The 2004 Nissan Xterra was part of the first generation, and the parts within that designation will often be compatible. This is also the case with the 2009 Xterra as it is included within the second generation. The two years are not compatible with each other. However, aftermarket options are available for both model runs of cars.

Why do the RPMs change when the blower is on?

Some change in your Nissan Xterras RPMs is normal if youre idling. Maintaining an idle of 700 and 1,000 is a normal range for your Nissan motor. The car is programmed to keep from overheating and conserve fuel. As a result, the Nissans RPMs will change as it adjusts to the HVAC system. The direct drive blower on the vehicles heat and air system is tied to the engine, and the speed of each application affects the other.
