I was driving my SRT6 today, and I turned on the AC. A minute after I turned on the AC, I was sitting at a stop light at a busy intersection and I heard a noise from under the hood like a belt broke and the car shut off. I turned the car on, and it was running OK, so I moved out of the intersection and pulled over when it was safe and looked under the hood and everything looked OK. I continued driving and again I started to hear noises like there was a belt issue (sounded like a belt was slapping around). I turned off the AC and the belt noise went away. I drove the car around for a while and it was fine, but didn't engage the AC. When I got home, I engaged the AC in my drive way, but the noise never returned.

The car hadn't been driven in about six months, so I'm wondering if the AC compressor was stuck? Is there anything to lube on it? I'm a bit concerned about engaging the AC after todays incident.

Thanks!

Compressors usually squeal.
Flapping sound sounds like a fan issue. Check the cooling fan for interference. Maybe a critter built a nest, been known to happen (but usually in the exhaust )

 

It seems to be related to the AC as when it's turned off, it's fine. I did a drive way test with the AC on and couldn't replicate the issue, so I'll do a road test driving around the neighborhood next and see if it comes back. Hopefully I don't need a new AC compressor

 

Fan will turn on with the AC even if the engine is not hot. Not that it is the problem but worth a look.
Good luck with it, hope it is not a compressor.

 

Your 1st post asked about lubing a compressor. The compressor clutch is press fit onto the compressor shaft. Need special tools to do it. No lubing there. As for internally, compressor oil (PAG oil) flow throughout the AC system along with refrigerant. Generally compressors when new come with 300 CCs of oil in them. when you replace individual components separately you're to add oil (evaporator, condensor, receiver drier/accumulator, etc.) But you'd need low side service port fitting to add oil. NEVER NEVER NEVER charge to the high side. Always service the low side.
