It could be freon, it could be various other things.. Have your freon checked first
there may be a faulty thermister behind your glove box . it regulates the temperature of the a/c...be sure your freon is up to specs before
you begin troubleshooting the system
No, there is not a reset button on the Nissan Xterra. However, there is a reset button on the clock in the Nissan Xterra to change the time. To reset the car, a technician would have to use their computer.
If one needs to buy Nissan Xterra parts then the best place to try would be your local Nissan dealer. Other possible retailers include Nissan Parts Zone and Everything Nissan.
If the system has a full charge then the thermister is most likely the cause for it not working.
The oil dipstick in a 2000 Nissan Xterra Se would be located under the hood of the car. It would be located on the right side of the car and have a yellow colored cap.
Where it would be regularly but behind a splash guard you have to remove
A bent valve(s).
A sixteen year old may have apprehension about driving such a large vehicle as a Nissan Xterra. You should talk over major car buying decisions with the 16 year old. However, the Nissan Xterra has great safety ratings, so it would be a good option for a sixteen year old.
You would disconnect the battery terminals.
I would try a junk yard in your area. Otherwise, you can order one from any Nissan dealer.
If you mean the fuel pump assembly yes. Fuel assembly is vague. But I assume you are referring to the fuel pump and float assembly that lives in your gas tank. There was a recall on some of the Xterra's because the wiring to the assembly was not protected well, the wiring would break and cause the Xterra's to die while driving without warning or you would come out to start your car and it just wouldn't start. You can call a dealer and give them your vin # to check and see if this recall has been performed on your vehicle.
I know that the ECMs are the same. If the mounts match up I would go for it.
One can purchase a 2000 Nissan Xterra from the following places: Edmunds, Kelley Blue Book (KBB), Yahoo Autos, JC Whitneys, Crutch Field, Auto Anything, Car Gurus, Auto Parts Warehouse.
