Squeaky AC

Hello,

I have a squeak coming from my air conditioner compressor. It only occurs when the AC is on - right when the AC clutch engages. The squeak matches the RPM so as I accelerate the squeak frequency increases as well.

I'm assuming it's a problem with the clutch itself but am looking for suggestions on what the actual problem may be and what options I have for repairing.

This is on a 2000 Boxster S with 86K miles.

Thanks!

Have you tried spraying some lubricant on the pulley? Are you sure it isn't a crappy belt? What so far have you tried to remedy the annoyance? Have you googled what might be causing a compressor squeak? Details, man. Details.

first things first: replace that belt. 95% the squeak goes away, if it doesn't, then let's address from there.

Haven't tried to lubricate the pulley, have a belt on the way so I'll replace it and see if that addresses the issue first.

You can put a bit of dielectric grease on the belt and see if it goes away. If it does, then it's time for a new belt.
