Short update for me –
Sounds as if the AC compressor is dead again.
Perhaps mentioned that i'd swapped out for a used spare and had it regassed last year. Also changed the pressure switch (and radiator) at the same time. After a couple of months it ceased blowing cold air, thought perhaps the shop had failed to check for leaks effectively.
Took it for a look yesterday (hey, just in time for summer - again!) and they reckon the compressor won't fire even when directly powered, but suggested taking it to an auto elec to be sure before changing it out.
Read a bit about modules etc which sounds painful.
@paul0075 @Philia_Bear do either of you have a spare used compressor in your stores?
