Fixed our noisy AC/Heater fan and leaky duct work.

You mean between the evaporator and the heater? Checked that, ours is still good.

Nice work ripper.

Any suggestions for getting crud out of the evaporator fins (that don't involve degassing and removing it first)?

Cheers,
Rick

I thought about how to clean the evaporator fins (as you can see, ours aren't great), but other than a quick blow with the compressor decided to leave it alone. Have to be careful or the air pressure can bend all the fins over.
Our local auto sparky is really helpful, might ask him if there's something good to clean them with.

Yours are pristine by comparison. I've tried vacuuming, including with a smaller diameter hose taped into the nozzle to up the suck per unit area or air velocity (whichever comes first), while scrubbing gently with an old toothbrush. At least I think it was an old one ... hmm, might be in trouble with wif. Moved a bit of it but it goes deeper, much deeper. Maybe I'll try the local carwash vac for some more powerful suction.

If you can come up with something from your bright spark I'd be most appreciative.

Cheers,

hi
what we use as work is a short piece of copper pipe bent to 90 degrees with the end almost closed attached to the hose we remove the fan speed resister that bo that goes into the side with a heap of wires coming out of it and with the help of a torch clean the whole evaporator this generally works well as most of the mud is dust hitting the wet evaporator and sticking we normaly keep quite a few rags underneath and near by to keep the water at bay.

Well at looong last I remembered to ask him about it. Unfortunately he doesn't have any magic solution. Sorry.

This sounds like the best you'll get if you can't pull it out to clean it. Thank you.

MK driver and my A/C needs some attention, trouble with this one (MK) A/C only works with internal air (combination switch, you want recycled air you get it air conditioned) but not very much of it. I will follow your lead and check what the fan etc is like, photos are great help too, thanks.

Cheers
