Clanking prior to AC blowing hot

[SixFootSix]

I’m in Las Vegas, It’s 90-degrees out and when I start my 2012 5.0 the AC Compressor sounds like it just destroyed itself (loud tapping and clanking noise) until I turned it off.

The AC has been working great up until this event occurred while out for a slow drive through the local hills.

The car sat turned off for about 20 minutes while I got out and walked around. When I returned to the car and started the engine the AC Compressor sounded like it mechanically destroyed itself.

I suspect this will be a costly repair on a 10 year old Genesis. I’m also not looking forward to the long drive home through the desert.

Costly on any car. I'd check out a local AC shop rather than the dealer. The dealer usually wants to put in a factory new while the local shop may be able to rebuild or get something more cost effective.

I don't think I ever has a 10 year old car that did not have an AC problem at some point.

Your housing could be cracked. Apparently our AC housing is made of plastic. It happened to me where I heard a ticking/clanging noise and wasn’t getting cold air. Forgot what I paid but couple hundred bucks for parts and labor.

Thank you for your reply. It was very hot in the desert and the road was recently paved with fresh black pavement. I’m sure the heat played a role on the 109k miles setup.

The AC Compressor has been confirmed seized and the plastic internal pieces of the compressor clutch gave their life to allow the belt to still turn. Certainly better than the alternative of being dead in the desert.

Now I just need to identify which model Compressor the Oct 18th 2011 Genesis used.

You do realize that if the compressor seized, it contaminated the rest of the system with metal scrapings from inside the compressor. If you just replace the compressor, you will be doing it again soon as the contamination will destroy the new compressor. The correct steps are to replace the condenser (due to design, it can't be flushed), replace the txv, replace the dryer, and correctly (multi-step process) flush all the lines/hoses and the evaporator.
