2002 Camry 4Cyl noise from AC bearing

[toyo9494]

Anyone experience noise from AC bearing, noise sounds like coming from exhaust, but had it checked out, mechanic used something like a doctor use, and check numerous places, and told me that it came from the AC bearing, only hear noise when in gear and when initial starting, disappear when car accelarate a bit, won't hear in neutral. Any advice. thanks, I was also told not to worry about it, AC works fine, noise just come when starting slowly, even hears it in reverse. ( exhaust is in perfect condition )

there is actually a TSB out for the early (2002-2003) model gen 5 camrys for an upgraded a/c system to improve its performance...maybe that will cover the issue?
this has been applied to my 2003 before i bought it as certified pre owned back in feb 07, and my a/c worked flawlessly all summer long with no noise whatsoever.

here is said TSB...
it mentions something about a metallic noise, which comes from the compressor...this might be your issue
hope this helps

TSB UPDATE NOTICE:

This TSB updates EL004–03. TSB EL004–03 is now obsolete and should be discarded.

Some 2002 – 2003 model year Camry owners may experience a condition where the
blower volume gradually decreases after about 1-1/2 hours of driving. It has been
determined that, in hot high humidity conditions, the A/C system evaporator is freezing
over, blocking the airflow path. There may be some instances where this condition may
affect the A/C compressor and clutch assembly. An in–line thermistor resistor harness is
now available to correct this concern.

Thanks for your input, my situation is this, I never have any problem with the AC since purchased new ( AC works fine, never failed once ), the only thing is this noise ( happened about two years ago ) only when I started to accelerate the car, ( noise is like those people put in low noise muffler ) but only for a very short time, once the car pick up some speed, and the noise is gone. especially very loud when in indoor garage and doing parking, ( cause I will be driving in very slow speed ).

If it really is the compressor, you should replace it before it fails completely and scatters debris throughout your entire A/C system causing damage do other componants. Getting all the debris out of an A/C system can be difficult and lead to other failures down the road.

Waiting will only cost you more.
