Default 2008 STI AC pulley, smoking and leaking fluid.

A few days ago my AC wasn't working properly, on full blast it had no power.
today I heard a weird pulley noise much like the idler pulley problem on the 04 stis. 30 minutes into driving, I smelled something burning, pulled over to see that some fluid was leaking from the AC pulley. Is this a common problem?

Sounds like the AC clutch is gone or you may have a front seal leak on the compressor or both. No, neither is normal.

Yes, just keep the AC off. The compressor is likely seized and you're seeing compressor oil leak out. If the oil is on the belt or mag clutch, those are going to need to be replaced too so hold the dealer to it. (most new compressors come with a clutch though so it will likely get replaced anyway)

If you turn the AC off, the clutch pulley should spin free and not try to turn the bad compressor.

I would worry a bit though if it's a seized compressor. Typically when they go, they produce a bunch of metal crap (shavings etc) that make their way throughout the AC system. They will (well, they can) block/plug the condenser, evaporator and expansion orifice and lead to problems in the future. In reality, if the compressor has seized, the dealer should be replacing/cleaning/flushing all these components and I'd be stern with them to make sure they do.

I've heard of way too many people who have been burned like this. Compressor seizes and puts contaminents into the system. Mechanic replaces the comp, recharges the system and it works for a few weeks. Then the orifice clogs so that then gets replaced. Then it clogs again because no one cleaned the system out. Then the new compressor fails because it gets starved of oil because the orifice clogged. Then if they get that all sorted out, the system never cools as efficiently again because passages in the condenser are clogged, etc.

It is a system. It needs to be repaired as such. Good luck!
