No Heater, except when driving fast!
Car only produces heat when traveling at a constant speed (highway travel). As soon as the car slow or stops heat changes to blowing cold air.

The Altima was redesigned for 2002. It grew significantly, bumping it out of the compact car class and into the midsized sedan range. It was even larger than Nissan's flagship Maxima. For the first time, a V6 engine was available.
The 2002 Altima came in four trims: the base model, the midrange S, the plush SL, and the top-of-the-line SE. The SE came standard with a 3.5-liter, 240-horsepower V6, and the others had a 2.5-liter, 175-horsepower four cylinder engine. All models came with a folding rear seat, power doors, and a tilting steering wheel. Upgrading to the S got air conditioning, cruise control, remote keyless entry, and a CD player. The SL included a power driver's seat and an upgraded sound system. Upgrading to the SE got the bigger engine, foglamps, and bigger wheels.
Drivers found the new Nissan Altima to be much better looking than the previous version. Owners still praise the car's value and reliability, and say that while the V6 engine is a nice addition, the four cylinder offers so much pep a bigger one isn't necessary. Many find the interior to be unpolished, and the addition of optional features can cause the Altima's price to approach that of the Maxima.

What years and models will interchange alternator with mine
I have a 2002 nissan altima SE V6 3.5 the battery wasn't staying charged so I changed the alternator and put in a new battery. After making sure all fuses were good and everything was hook up as suppose to be I went to start the car and there was no power at all. No light no dinging , as it does when u put the key in the ignition, nothing at all.! Plz help!!!
i have a 02 Nissan Altima that just had a used engine put in. After we got the car running I've noticed it will idle up nd down. It will only do it in park, i do not notice it in drive. Also it doesn't do it all the time. but when the car isn't reeving up and down it will idle high at about 2000rpm. it has also flipped the check engine light. Before the motor that was placed in this car, the previous car it did not run this way. It did perfectly fine.No noticed in gas milage change or performace in engine. what could be wrong and what do i need to look for to fix it. its getting quite annoying. Thank you
