I've been working away on Andrews NSX and will upload the complete work when I'm finished. But in the meantime I would like you guys to see this and with Andrews permission, I have attached the pics below.

To make a long story short, the complete AC system was not functioning on the car, compressor is shot, CCU was fried and Andrew had told me about a bad smell coming from it on his journey home after he purchased it.

So while I was working on other items I sent the CCU to Kaz for repair and as always it was returned in tip top condition.

So as a quick test I installed the CCU and immediately I could smell what Andrew was talking about, which was pretty bad to say the least. On removing the blower I was pretty shocked to see this!!

From what I can gather its a fungus that has grown on the evaporator and although you can only see a bit of the evaporator, it has grown on 95% of it. Its also welded on pretty tight and with the fins being so delicate I'm kinda stumped on best method to clean this as obviously to much water and chemical means it will run inside the car. Now I'm not bothered about the carpet getting wet as that will be removed and I can mask off and remove most of the electrics that are near by, but just unsure if air and chemicals will remove this.

Any thoughts?

If it is a fungus than it will hazardous to the lungs and and potentially cause permanent lung damage...aspergillosis!!!
If it can be cleaned off properly..you may have to get a replacement!

Yeah I already told Andrew the bad symptoms that can be caused by the fungus. I dont like to say it but, I'm really stumped on best method of cleaning this up with out having to remove it completely.

For gods sake!
I don't see any other possibility than removing and maybe replacing the A/C heater. It's a lot of work but is said to be not very complicated. The dash needs to come out.
Good luck!

An A\C specialist may be the best person to ask. There's got to be a chemical available to neutralise the fungus. Maybe alcohol?

A friend of mine is an A/C specialist, and although he hasnt seen the car yet or a photo, I told him about the evaporator in detail, to which he didnt sound too enthusiastic about, especially the trying to clean it correctly with it still in the car. He does use chemicals/alcohol/air/brushes to clean A/C units but, he was concerned about how deep into the the evaporator the fungus has spread, obviously access to it from the front is quite limited and with it being a fungus he said caution needs to be applied especially if using allot of air so that your not blowing the spores into other parts of the car where it could settle and also as Kare mentioned, its hazardous to the lungs and your health. He reckons the only true method to clean the one in the car is removal and then steeping it for a long period. Also other parts of the system would need cleaned and disinfected too. I obviously have the blower out and removed the motor and turbine thats inside and it all smelled terrible.

....what are you waiting for then? Get it out!

Not my car lol! and was hoping there may have been a simpler solution, not just for me but obviously for Andrew as well as its quite a time consuming job with the removal of the dash and all the electrics involved. Andrew is calling to mine today so I'll be showing him the unit and see where to go from there.
