Definitely have that recirc vacuum servo problem going but until today I could always get cold air by goosing the gas and then letting up. After a hard turn to the right it blasted hard for about one second and then went kaput.

Fan not working on any setting.

No evidence of hot/cold air anywhere regardless of venting direction/setting, although I can hear the various doors activate and the compressor randomly kicking on.

Recirc light is on randomly regardless of button position or venting direction.

AC OFF button light works properly.

Air intake in passenger side footwell appears to be clear.

Vacuum hose intact (per technical gallery photo, below.)

Fuses #19 & 28 are good - even when swapped out.

Ran ECC diagnostic per 'FAQs for 700/900' - only code is 111, which is NO code.

Ran the OBD-1 (connector B, socket 1) for further Dx, could not get it to work.

Possible ECC board cracked solder?? How to find & remove?

Drive it off a cliff?

I'm cross-posting this to the 900 forum...
