Do you recommend running the AC system all year and not just in the summer?

@stevemartegani says:

I had two A/C issues I haven't seen anyone discuss before happen in the last couple months on my current project.

Installed the AC system I had lying around for awhile onto my originally non-AC 93 Impreza. Filled the system with dye as well, and ran it a little while… The Compressor seal in the middle of the compressor failed! Nobody talks about that giant O-ring. The front seal failed too, neither of which are easy to find replacement seals for, so I just replaced the whole thing.

Then on the ride home after getting thr A/C system charged properly, the plastic idler pulley failed in such a way the plastic melted and stuck to the crank pulley and compressor pulley too! Had to chip off all the hardened plastic and also upgraded to a metal idler pulley and metal bracket to be safe.

I think that managed to damage the new compressor though, it makes a ton of rattle-y noise now 🙁

Not sure what lessons I learned other than "Anything that can happen, will happen" LOL

My 2004 llbean's AC button stopped working, doesn't send signal power to the relay. Have confirmed this is the issue several different ways, debating whether to fix it. It blew cold air through my road tripping last year which was great, impressed the system held up as it did.

Does anyone know what the hole to the right of the oil filter is for?

@CouchMan88 says:

2023 Subaru Impreza. A/C is a bit weak for a new car and compressor is noisy when it kicks on. Heater works like a charm.

@Gilbearrr says:

Great video. My 2013 Impreza has a zippy sound when I turn on my AC. Still working though.

@gsabella4 says:

2008 Forester here, my AC works great but my engine shakes/vibrates when the AC is on. any ideas?

@tekinozsoy3324 says:

I bought 24 wrx vb 11ks on clock drive home about 10km driving easy,,,pulled um in driveway turned off,,,and all off a sudden alot of smoke came from under the hood,,,rezalet said was normal but I'm still concerned,,,any help would be appreciated thank you

@westdccs says:

On the noise of the clutch on the FA engines, would this explain a loud grinding sound on a cold start? I have the FA-20 (2015 WRX), and on a cold start there will often be a fairly loud grinding sound when the A/C clutch engages the first time. It's fairly short, and it will only happen on the first cold start of the day. If I drive to work and park for an 8 hour shift, starting the car to drive home the noise does not return until the next morning.

My 2017 legacy Has had abysmal ac from day one. It was really disappointing, But if it's that hot, I'll just drive my truck with 10/10 AC

@TheGhungFu says:

……… or you can just roll the windows down.

@allenrider5810 says:

I had the compressor clutch control relay go bad in my 2007 Outback. Easy replacement. That was three years ago and all still good.

@Doug_Hefernen says:

My 08 Outback AC compressor clutch clicks on and off, where do I look first?
