Changed battery, and now A/C doesn't work. Turning on AC with small rotary knob activates both radiator cooling fans, but overrides the ventilation fan, and blows nothing through vents. Immediately before changing battery A/C blew very cold. All fuses in place and good. Thinking it could be Relay III - Air conditioning system. Has this happened to anybody else? Thoughts? Thanks!

Resolved.
The vacuum hose leading from the vacuum actuator (?) to the connector sheath inside top back of the engine bay was disconnected. Plugged it back in and bingo!
What's quite extraordinary that this isn't mentioned anywhere that I could find in the many pages on the subject in 924, 944, Pelican parts and Rennlist forums.
