Belt squeeks!!!
I have a 98' which was bought 3 years ago. It was squeeking after 2 weeks of the day i had bought it. I had extended warranty so I took advantage of it and took it back to the dealership for them to fix it. I was told that it was the Harmonic Balancer needed to be replaced. So I had them replaced that. And the squeeking stopped. 5 months later I replaced that new balancer with an after market BBK UnderDrive Pulley and still no squeek. Untill last week every morning that I start the car...I get this annoying squeeking noise. And it just seems to get louder as I accelerate and stop when I let off the gas. I tryed spraying the belts with Anti-squeek that i got from the autoparts store but it didnt do a damn thing. I still get hear that annoying noise. Anyone know how I can fix this? I havent changed the belts yet...(I am going to buy the Gatorback tonite to see if it can cure my problem).

A/C pulley gets worn & mis aligned..
Also the belt tensioner pully..
How to figure out?
Take off the serpentine belt
Start car, if no squeek, belt tensioner...
If there is still squeeking, its the A/C pully..
Also the belt tensioner pully..

I think you are going to have to do your test on a day when you have time.
Start the car until it just starts to squeak then turn it off and pull the main belt.
Start it again and if it squeaks, it's with the AC belt.
I just replaced my AC tensioner a week ago because of this.
I also have the BBK UD pulley, but that's not the cause.
The tensioner bushings inside wear out and put the pulley out of alignment.

Check that for sure. A friend had the same issue and that's what it was.

I am having AC problems also. When I turn the ac on after like 30 secs a LOUD screeching noise coming the middle vents starts. Even when I use Defrost. I have no clue how to fix this. Has anyone else had this problem before? Do I need to recharge my ac? As of right now I dont have AC or Heat. I tryed changing the fan speed but that didnt do anything to make the noise stop or quiet down a little.

Squeaky belt
How does it go? You can't see the forest for the trees. I did everything I could think of to stop my belt noise in my c6 vette including replacing belts and pullies, with no luck. So I thought what if the belts have to be absolutely clean. The reason I say this is as a last resort I used belt dressing and the noise got even louder. So I decided to remove the belts and clean them and the pulleys with 409. I let everything dry and then reinstalled the belts. Believe it or not the car actually runs smoother and quieter. All righty then, Ok by by then.

About every 3 months my A/C belt starts to squeak. When this happens, I smear a drop or two of silicone oil on the belt and the noise stops. I suspect the squeak is caused by a slight shaft seal leak on the water pump. As mentioned above, cleaning the belt would probably do the same thing but the silicone oil treatment is easier.
