2002 nissan altima revs up while idle

My 2002 nissan altima revs up while idle. Also when i turn the heater/ac on it makes a loud noise and vibrates. It's very embarrassing when I come to stop sign or red light. I have to turn the heater/ac off. I turn it back on when I take off. Is anybody having the same problem or have a solution?

My car has done the same thing. . I have replaced the tensioner and belt twice now and it will start it again within a couple weeks of replacement. Had it looked at again and there is nothing wrong with it! just an embarrassing noise. dont replace it, its a waste of money.

I had the same problem, you can replace both the acc band and the band tensor, the vibration comes from a loose band.

2002 Nissan Altima Cold air blows at idle but is warm at higher engine RPM


Heater core may be clogged. Try flushing it to see if water flows through freely. Also check the heater water control valve for restrictions.

2005 Nissan Altima makes rattling/vibration noise


It is possible that you have some timing chain noise, especially if you have the 3.5L engine. The secondary timing chain tensioners on the 3.5 have a known problem, Nissan has issued a service bulletin regarding this and there is an updated part to replace them. It is not a cheap job, but your dealer may give you some "goodwill" depending on your mileage. If you have the 2.5L the problem may a couple of other things...even more serious! They had catalytic converters that came apart and got ingested into the engine, eventually destroying it. Try googling "Altima rattle" and include your engine size in the search. There is a ton of info on the net about noises in these cars.

2003 Nissan Altima, Air condition makes loud noise when the unit is turn on. It slows down where u cant almost hear it after you turn the fan off.


When you put your A/C on, there is Vacum Motor or Solonoide, that increases RPM of the Engine to compensate the load of an A/C. If the vacum hose is leaking or raptured the RPM of Engine remain low and Engine Shakes. When you put the A/C on and the RPM of Engine Increases, but a little, then your Selonoide is working but not adjusted properly, so adjust it for the proper RPM of the Engine. Put all the loads on, I mean Head Lights and A/C on and then ajust the RPM.

VIbration in AC/HEATER fan


I've had mice in my Nissan PU and actually caught one in a trap set on the floorboard; so I know they can get inside. They also knocked some of the fiberglass insulation into the blower motor so it vibrated as it was no longer balanced. You could have a dead one in your blower. Mine was easily accessible from under the passenger side under the dash. Three screws and the motor dropped so I could clean out the fiberglass.

Why does my car vibrate and noisy at red light and stop sign


My rio kia bought on from uyi technical dealer in benin city, edo state of nigeria only 4 months ago is vibrating with noise while driving. The noise is noticed by other road users even in motion, making a very loud noise or sound that is highly embarrassing. The dealer mechanics have checked more than twice yet no result, instead the hub bearing is observed; tyres are turn over yet the noise persists.

What do think is resolution to the problem? pls help me. Vinson- kvinson3000@yahoo.com

02 altima belt noise


OK, went through the exact same thing this week. Put on a new belt, checked for proper seating, etc, etc. and that wasn't it. Read all through this site and others and it comes down to one of two things, the tension pulley assembly or the compressor itself. Seeing as compressors ran about $300 or so and the pully assembly is less than $50 and takes about 45 min to an hour to replace, I did that first. And for me, that was it. Tip for replacing the pulley assembly? Have a wide variety of sockets (depth) and extensions.
