Problem: Powerloss and whine when the A/C is on...
.. Recently, i've started the use the A/C more since it gets real hot out now.. so I was driving around and noticed the air conditioner is really weak. I was on full blast and it was not very effective, it cools but not so well. So I thought i just need to recharge it.
Later, I noticed that the car feels really sluggish, I know that cars don't perform as good with the A/C on but it was REALLY bad..
then, I noticed that when i get to 3k RPMs and above, there is a noticeable whine coming from somewhere... sounds like a ghetto blow off valve..
so what can this be?
My guess is the A/C compressor belt? but what's happening, is it slipping or can it be too tight? i checked it and it seemed alright. A bit hard though...
how do i go about in fixing this problem?
thanks

any way i can single out the problem? check resistance or something?

Before you spend a dime on A/C charging or diagnosis, be sure you replace your cabin air filter (if you have one).
A clogged cabin filter will reduce airflow and cause whinning noises from the interior fan. Had a similar problem with my previous car...replaced the filter that helped.
There are on-line tips in the forum on how to replace it.

i had two cars now, and the ive noticed when the AC is on, the car is slower at acceleration...... i think its normal since AC drains a lot of gas. I might be wrong. someone can ad to this.
On the whining part.... my AC whines.... really low whine, i guess thats the noise of the Ac compressor.... guess its normal....
