Squeaking noise during acceleration

My boxster is making a squeaking noise whenever I accelerate- it stops however when I reach around 3,000rpms. It's coming from near the rear left (driver side) wheel. Also, if the car it idle and I turn on the AC, it will instantly trigger the squeaking without even accelerating. Is it some belt?

There is only one belt. Easy DIY job. Cost $30-60, depending on what brand and where you get it from. Takes longer to take off the access panel than to change the belt. Just make sure you follow the proper sequence of which pulleys to put it on, otherwise you will swear that it is too short.
Check all the pulleys and accessories that are driven by the belt for bad bearings while you are in there.

OK, I ordered one on eBay... If the belt snaps before it gets here, what happens? Does the car stop driving?

Hey guys, I changed the belt and it's still squeaking. I know it has something to do with the air conditioner because when I turn it off it kinda stops. Any ideas?

It could be your a/c compressor. If it's bad and the clutch pulley is sticking, it would make a squeaking noise at certain rpm.

Thanks, but how can I accurately diagnose and fix it?

Tighten all the spark plugs, it will be gone. 986 motors loosen plugs when they do the sound is like what you describe and goes away after three grand on the tach as you said.

Well since I don't have a garage and it's been raining everyday, I called the dealership and asked them how much to change my plugs. (It's been over a year now) and they said it would be $300 but didn't have anything to do with the squeaking.

Ouch! $50 a plug to change... I would try just tightening them first. How many miles are on them?

Maybe 5000? They need to be changed anyway, but not by the dealership!

It might not be them but if your dealership claims a loose plug does not make a noise that resembles a squeak they are mistaken. Some models have windows in the splash shield behind the rear tires to get to the plugs. They are not hard except the very fronts and having a short enough allen to remove the coil packs.

Is it true that I need to lift the car up and take off both wheels to get to the plugs? I only have the jack that came with the car.

(I don't believe the dealership for 1 second)

It's easier with the wheels off, with only the stock jack it's unsafe to slide under even with the wheels on. If you can barrow some jack stands you can do one side at a time, might as well replace them. You will need a metric allen set for the coil packs, long extension and flex coupling for the plug socket. Best to have a torque wrench for the plugs (don't know the factory spec) but in a pinch you can just make sure they are a bit tighter than snug, I also suggest using Bosch plugs.

Sounds like your ac clutch is making the noise. Not too serious. Look into having it rebuilt or buying a new one using your existing one as a core.

Sounds pretty serious to me. I can't even get my car off the ground to change the plugs... You have no idea. Where I live, the dealership is the only game in town.

Sorry about that. Are you in the Big Easy? - I'm fairly sure that's what it is though. I'm not 100% sure but I think you can rebuild the clutch part that's making the noise. Do a search on this forum and see what others have done with the same problem. A whole compressor unit is going to run $450-$500 but you don't need that. I'm thinking there is a solution for the squeaky-clutch only. Good luck.
