I have a 2000 Nissan Maxima with almost 93,000 miles. When I first start the car, there is a small squeak lasting only a second or two. If I turn the heat on, it makes a very loud sound (not a squeak, more like a rattling sound) but if I turn the heat off, it makes no noise; the car sounds normal. I had the serpentine belt replaced in September or October of 2005. No other work (other than oil changes) has been done since then. Like I said before, it only makes the loud rattling sound when the heat is on. Please help. Will my car break down on me?

The sound is coming from the engine near the front.

The AC doesn't come on when I turn the car on. It only comes on if I manually turn it on. The heat/AC still work normally, it's just that when I use either the loud noise starts. It will stop if I turn the heat/AC off.

I agree with Mr Know, but there could be other reasons. Squeak could be coming from one of the belts. As for the noise, you didn't say where you can hear it. Is it coming from the front of the engine? Is it closer to the air vents inside the car? If it sounds as if it is closer to the inside, it could be the small fan, the one that blows air inside the car.

A/C compressor bearings are worn out.
When you start your car, the A/C turns on briefly.(about one second)
When you turn on the heater, the A/C turns on too.
You may want to seek professional help.

either some debris is in the fan motor or the motor bearing is worn.

I'd guess there is a problem with the blower motor.
