I notice a strange sound when accelerating/rolling, it kind of a " Wizzz" ... Like something who's suppose to follow th rev of the car, but having restriction ...
Sound if present when using the a/c, but everything work fine ( maybe a/c is a bit hotter ... But still cold ... )

We have very hot days for a couples of days ( 90-99 F ) with humidity ... The sound doesn't seem to be there in the morning ( 80-82 F ), but when i'm close to job, I'm starting to ear it ...

Any idea of what it could be ? A/C clutch ? SC failure ?

No one ??

 

You answered your own question....
"Sound is present when using ac"....
Your ac...it uses expanding gas to make cold.....so likely hearing the expansion valve...
You MIGHT be hearing the PS pump fan....they can make some noise when the bearings are failing.
Some of your descriptions are hard to understand...but that is why all guesses on sounds for car repair is just a wag....

 

+1 on what zippy said.

When you turn on the A/C , kicks on the front fan and the PS fan. Also when you engage the A/C the pump clutch will engage and sometimes sounds like a very low whirl with the drive of the engine.

Always check you lower Power Steering Fan to make sure junk is not clogging the fan and plastic bags or road debris is not caught in it. You are an 2002 so you don't have the grille unless its been updated to the new one. Its located on the bottom of the engine right behind the oil pan.

The whirl is pretty loud in the afternoon ... it seem to have something with temperature, I went out this afternoon and it was raining ... i almost never heard the whirl ... and it still was hot ...
