Aw, Plankton, I don't suppose you want to re-title this thread? Your problem is far too specific for such a generalized statement, IMO.
Agree, $4000 is a ridiculous price to fix anything on the car… I simply wouldn't do it and would try to be creative. I take it this is after you had paid Mitsu $400 to replace the a/c bracket (which, I'm afraid, I wouldn't have done in the first place)?
Presumably you've escalated the issue with Mitsubishi, as it looked as though there was the beginning of a trend in cold-climate i-MiEVs?
Have you tried third-party aircon repair shops?
I presume the heater works fine? What about when running the heater and dehumidify at the same time?
As someone who drove for over 40 years before getting a car with a/c in 2004 (Gen1 Honda Insight), I can't get excited over not having air conditioning. Even now, and despite our present heat wave, I drive our i-MiEVs with windows open and no a/c… but, then again, I don't live in Arizona or the US South or SouthEast…
Regarding care and feeding of automotive air conditioning units, I understand we should exercise the darn things periodically(?). Anything about NOT running the a/c in seriously-cold weather?
Plankton, on the previous thread you had been posting to, would you be kind enough to update us with your blow-by-blow tribulations with Mitsubishi regarding this problem?

Would you mind if I moved these posts into that thread?
Thanks, and good luck.
